Hi, I need some UV paint that is inviable under normal light that turns bright white under blacklights. I will painting it on a giant hanging sign. I need a recipe for some uv paint or a cheap source of it. It looks like it cost around $70 dollars for 1 gallon and I need around 3 gallons of it. I know that you can use tonic water but I don't have experience using it (How bright will it glow). Also you can use laundry detergent but I dont know if it will show in normal. The key is it to not glow the under normal light and for it glow brightly under uv light, and it needs to be cheap. Any one have any experience with uv lights, paints, or other related things. Any comments are welcome. Thanks for your time. Joe R

I wear eyeglasses and like having the photochromatic lenses. But the problem is, while using them in my car, when I need them most, the UV protection built into my cars windshield and windows, prevent my glasses from turning dark. My question is : Can a small, battery powered or car powered, light array be built using UV producing LEDs, assuming there IS such a thing, that can be switched "on" to make my photochromatic lenses turn dark while driving? Maybe have it clip onto the sunvisor, or attached to the overhead center console, aimed toward my face. Thanks

I am trying to figure out a way to make a switch that is activated by a UV light. I have looked all over the web and cannot find a thing on this subject. The reason that I am trying to do this is that I recently purchased a Sonic Screwdriver that has a IV light in the end and I was wanting to make it turn on/off things with the push of a button.

Alright less of what kind I need more than what will work. I want to buy one of those LED work lights (that go for around 40 bucks) to UV, however according to this list I would need 365 nm LEDs http://www.riskreactor.com/Black_Lights_UV_LEDs/Black_Lights_UV_LEDs_Main.htm so my question is, would it be better to go with 365 nm? Thing is those are way more expensive than 380 nm leds, but you can do some neater stuff with them. So, would it be worth spending the extra on them, and do any of you know a place I can get them that don't charge a ridiculous amount for them? Also, would it be a good idea to perhaps mix the LEDs that way I get the stuff you can do in 380 nm and 365 nm? would that work?
Asked by XOIIO 5 years ago
I was wondering if this is doable, or even practical for that matter. So I read up on lasers and from what I can tell it is a form of light in which the wave frequencies are perfectly aligned. So I was wondering if you aligned UV light wave frequencies, would you get a laser that would burn stuff, and not to sound morbid, but in high quantaties, kill people. (Only for the sheer exitement of figuring something out am I posting this. I do not in any way want to kill someone.)

Year after year the topic "I have a fish tank" seems to go more out of control. What was once a hobby just to have some fish can now be a design feature both in your home and inside the tank. Realistic looking lasdscapes, optical illusions that make you think the tank is much bigger and the list goes on. But one thing that now always pops up is the must have thing of UV filtration. Or to be precise: UV-C sterilisation! Now, if we trust Wiki and our big water suppliers then UV-C will literally kill anything alive that comes into contact with. So of course it would be a good thing to have for your tank - or not? UV-C is very dangerous for your eyesight and quite harmful for your skin! Looking into a proper UV-C lamp without protection means you can go blind! Even good sunglasses might not have enough protection in the UV-C range, so only use them for additional protection but never without and glass between you and the lamp! Don't be a fool! Treat UV-C seriously! You would not look into the full sun with your sunglasses and would not expose your eyes or skin to a powerful laser, UV-C is to be treated the same way! Let's start by using some boring text to explain the concept a little bit. On a large scale special and quite powerful systems are used to treat our drinking or pool water. Here special UV-C lights with a wavelenghts of 260nm or below are used to shine through the water passing by. There are two key factors here. a) the wavelenght b) the water flow rate and the corresponding time the water is in contact with the UV light To ensure all bacteria, viruses, algae and other harmful organics are dead the water must circulate for long enough so even the last water molecule had a few seconds of exposure. All this only works good with "crystal clear" water for obvious reasons as otherwise the UV has to be even more powerful to pass through. Single cell organisms literally crack into pieces similar to being exposed to gamma rays, more complex cells like algae have their cell membranes damages and the DNA suffers as well causing reproduction loss and early death. Even some chemicals break down, most importantly here chlorine based substances. Differences within the UV-C range! If you bothered to check Wiki about the topic of UV-C you will already know that only certain wavelengths within this spectrum will actuall be powerful enough to do what we want it to do. And here is the first problem for us hobby users. Most cheaply advertised "sterlisation lamps" you find in places like Ebay are actually totally useless. Stating to be selling a UV-C light to sterilze your water in such a case is still not considered to be fraud though. Simply because it still does what it supposed to do, just very slow and with very little effect. Only the so called "short wave" UV-C range is powerful enough! To avoid loosing business during the times of the biggest hype in 20 years no seller will actuall state the available wavelengths. That means without this info anywhere you can be certain the advertised lamp is of little to no use. Even those advertised to be short wave UV-C might not be the real deal. However, if a decent manufacturer is behind the actual lamp used it is possible to check the datasheet for these performance figures - but again most cheap systems come with no-name lamps inside. Check the prices for a reputable UV-C light with the same lamp fitting, e.g. G23 and you will see it might cost more than your entire system. Ok, you have a poper short wave UV-C lamp or consider getting a canister filter with one in it.... Never, ever test your lamp without proper protection!!!!! UV-C will damage your eye within seconds! If you system or lamp does not provide a viewing port or shine through area then you have to place a piece of glass between you and the light! UV-C won't be able to penetrate normal window glass but will pass through quartz glass. Place the lamp in a box and cover with the glass. How make proper use of UV-C sterilisation... The replacement lights are quite expensive, so let's see how to get the most out of them. As said before exposure is the key factor so the flow rate of the UV system must match tank size and flow rate of your filter system. Canister filters with a build in lamp should be designed to match but I will tell you later what to look for ;) Most of us will prefer to have a in-line system if there is already a good canister filter at work, so I will focus on those and rop in solutions. If you compare in-line system you might notice that some quite small and low power units claim to allow for the same flow rates as for example 40W units. Some are fraud and just want to sell while others use simple physics to make the claim true. A good system will utilise an auger like "ramp" that forces the water to circulate around the tube many times - causing up to ten times longer exposure rates. Others create this sprial effect more like a vortex with some diverters and modified inlets. The later seems to be less efficient though with low power lamps. An in-line system should be on the outlet side of your canister filter so the best quality water will pass through it. A drop in solution should be used alone and without the existing normal filter pump you might have in there. Ok, got it, but how do I actually use it now? Despite common thinking a UV-C system should not run 24/7 like your normal filter. You really only need it to solve problems you should not have in a healthy tank! It is not a magical solution to make your underlaying problems go away ;) Let's start with the most common reason someone buys a UV-C system: An algae or bacterial outbreak causing greenish or milky water. If that developed slowly over a period of weeks then you would be better off to do a good clean of the tank and filter plus a decent water exchange. A few drops of meds will do the rest. And if you constantly get algae growing on your glass, ornaments and plants then your nutrient levels and water quality is not right anyway and needs a good check. But of course there is also the problem of light - too much for too long and unwanted gree appears everywhere. If in doubt reduce the light power, shade out natural light or reduce the on time for your lights. Having said that we now face the problem of a sudden outbreak after introducing new fish or plants. If you don't have a quarantaine tank chances are that sooner or later you get unwanted or even harmful guest into your tank. Here the UV-C will be beneficial, which is why a canister filter with build in light should have a seperate switch or power supply for the light. After an outbreak or while introducing new life into your tank the UV-C will remove a lot of the things that we don't want to bring along. For new life I leave the light on non stop for a week, that is for a small 4ft tank with 200 liters. To control an outbreak it depends on how bad it is. I assume here you can still see the back of your tank but that the water either appears greenish or slightly milky from bacteria. As a personal thing I prefer to to remove and clean my filter material before treating a severe outbreak. Once done I fill the filter with a mix of activate carbon material and fine filter wool. Reason for this quite simple: The outbreak causing stuff is already in your filter material and will be a constant source of re-infection. And since breaking down all this bad stuff causes even more bad stuff to be produced as biological waste we want to discard it properly once done. Using just fine filter wool and activated carbon also reduces the flow rate bit if compacted ;) Now we can turn on the light and pump and forget about it for a while. It is not recommended to run UV lights on a timer as you want them on all time to prevent short lifespan and have ongoing treatment of the water. Good idea to take a picture at the same of a day from now on to compare and check results. After 3 days the water should definately be clearer, if not then either your filter material is packed too losse or the lamp is no good. Once the water appears to be clear do a readin test - take a newspaper behind the tank and check if the text is clear - blurry means the water is still not clean. You will reach a point where the water quality will not further improve as much as in the days before. This is the time where you discard or clean out to dry your filter material and put the original stuff back in. The activated carbon should be discarded of course. You cleaned filter material will now need a certain time to grow enough good bacteria to go back to the old performance. During this time you should still leave the light on. In most cases with enough fish and plants in the tank a week should be sufficient. After that you can leave the light off and keep the tank fit and healthy. Special case: Algae everywhere! Especially after getting a new plant you can end up with quite pesty algae growth. Be it these long ghost hair types or in a bad case the black stuff growing on plants, ornaments and the glass. I have even seen tanks with algae covering the entire bottom of the tank causing the gravel to look like carpet. Here I can only advise to set up a quarantaine tank for your fish. Then remove all infested material for manual removal and cleaning. Infested plants should be cut clean and what can be boiled should be boiled in water for a few minutes. Now start scrubbing in the tank with ongoing water replacements. I prefer to let everything settle over night without any bubbler or pump running. This way I can suck up a lot of sediment the next day. If you can remove all plants and fish you can now use hydrogen peroxide and add it to your tank water. But this is only feasable for small desktop tanks. Before using the UV as above to cure an outbreak you should consider all water one last time. Allow at least 2 weeks with ongoing water checks before adding plants back in and another week before placing your fish back in the tank. The week before adding fish should be used to monitor the plats for any signs of algae you might have missed - if you find any remove it! A week after the fish is back in you can turn off the UV light. Underwater UV-C light!? In most online stores you will find quite cheap UV lights to be advertised as underwater or in tank use. Although it might sound tempting you should be well aware of the dangers of using them. The glass of your tank will block the harmfull UV rays but the water surface won't, so either don't ever look at it or use proper sunglasses with real UV protection. Apart from the dangers to you these lamps are not just cheap in price but also cheaply produced. That means there is no way of telling how much or how little UV-C is produced. If they are good then you still need to know in what type of tank setup you can use them. As plants can tolerate a bit of UV a placement as far away from the nearest plant should do, especially if you can place a bubble wall betwenn light and plants. The fish is another thing as some seem to be unaware of the danger in their tank. This means they can get too close to the light but I have not found any articles explaining how harmful UV-C is to fish or their eyesight. I guess once your fish starts to bounce into everything you know... ;) My advise is to stay away from the idea of hanging a UV-C lamp in your tank, the risk for you and your tank is just not justified. If you need to go cheap then get two or thre of these lamps so you have spares. But use them externally ;) Meaning: Take a UV proof plastic container of small size and place the light in there. To be really safe tape the lid and all holes for the hoses with black tape. Place the container above the water level of your tank and if you only have an internal filter pump push a suitable sized hose into the outlet to feed into you canister. Check how high you pump can make it and place the outlet or overflow slightly below this level. When to change the light? If you made it all the way down here then you might already had the benefit of using light to "cure" your tank. Now we are faced with the high replacement cost for the lamp itself. Ususally only flouroscent tubes are used. It is always good to check after purchase what type of lamp and manufacturer (if there is one) was used. In some cases the system itself is like an inkjet printer: Just a cheap way to make you buy the consumables. Let's say you new in-line filter was priced at $100 to have a nice round number, some are cheaper some much more expensive. The lamp used might be an exotic type and not even be available easy, so before you buy your system check where you can get spares, not just the lamp of course. A replacement lamp can be as ceap as 20 bucks or cost even more than your system if you need to order it elsewhere. The quartz glass sleeve can break too meaning you then need a lamp and cylinder. Going with a reputable brand and paying a bit more certainly helps to get spares in the future. Let's just assume you either got your system in bulk due to the price of replacement lamps or can get them at a reasonable price. UV-C lamps are not like your normal flouroscent light tubes you have around or maybe even on top of your tank. Consider them like the tubes used in the now unhealthy tanning beds. After a certain amount of time they no longer produce enough of the short wave UV light that we need. As you can't see it and most of us won't have the means to specifically measure it we have to trust manufacturers recommendations. For most good brands the numbers are the same: 8000 hours max. Considering the costs it does make sense to keep written track of the usage. Not too hard since we won't use them like normal lights but instead have them on for a week or more without turning them off. I recommend to have a replacement at hand long before you need it. A lamp can fail premature, crack or simply burn out. The 8000 hours are based on 24 hour usage, so one day on, one day off. This could mean for us the lifetime can be slightly longer but I would not go over 9000 hours. As a rule of thumb: If the water does not show good signs of getting clear on day thre the lamp is due.

If there were a way to mod it into a black light, how much will it affect the range of good light? 3) Is there any way to connect the lighting to a battery pack or some sort of regular 3 pronged plug?

I'm in need of a couple dozen battery powered "throwie" styled (read: super simple) UV light emitting LED's for a board game prototype. The devices (12 total) will be built into simple chipboard player pieces on a stand. I'd like the entire piece (including the chipboard and stand) to be no larger that 1" x 2" x 1", but here is the catch! Each piece will start with 3 pegs placed in the stand (a la the classic board game "Life") that keep the light on as long as there is at least 1 peg in. Don't know if this would mean they are pressing a button or completing the circuit, but whichever is safest is ideal! I also need a 2nd version that will operate with a simple on/off switch or button that can be housed in a small piece of foam core board (.25" thick, approx. 2"x 2" piece). I need 12 of these as well. Concept sketch attached, but more detailed information will be provided upon inquiry. I would need them to be completed and delivered by Friday, June 8th, 2012.

I am currently trying to research this topic as I am looking into building a stereolithograph 3D printer. I have been searching for some time now with not a whole lot of answers. This is not my area of expertise so I could use some input. I have found lasers in the range of 256nm wavelength but it is going to cost me an arm and a leg. Even at the price range the UV lasers are only outputting at most 1W of power. I have read that UV curing resin is most reactive in the range of 265nm and that is why I have been searching for something in that ballpark. I have found some companies that manufacture LED in that wavelength but then the problem is going to be trying to focus the light down to a fine enough point. I am trying to design a 3D printer that is in the high resolution range. So, my true question is. Does UV curing resin react best with the 265nm vs the 400nm range as I could just a blu-ray laser. If it is better at the 265nm range, could I possibly be able to focus enough light from a couple of 3W leds down to a small enough point to cure the resin where I want it to be. The other idea is taking a UV laser in the 400nm range and focusing the beam down to get me fine but quick set up time in the resin. Or possibly multiple Lasers

I don' t have the technical or computer skills to make this happen, but I'll bet someone out there does. I've heard of and read about these polymer 3d model makers and I understand that a few colleges have them. I know that one in my area does, as it was reported in the local newspaper. I also understand that they are quite expensive. I've seen the Instructables for some 2D routing tables, and even a couple for 3D work, using a hot glue gun or some other flexible material for building the model. Crude results, comparatively speaking, but impressive from the standpoint of the home hobbyist. I've recently learned of a product called Solarez, which is a UV curing resin for fiberglass work. No limits on the working time of the resin, no gelling up in the middle of a job, it seems like a dream for complex fiberglass projects. Put it in the sun and three minutes later, it's fully cured. There are videos on YouTube for the fiberglassing aspect of things. They are not as exciting as the Instructables, but they are instructional. I plan to use Solarez in my future fiberglass projects, but I have a quart of very expensive epoxy resin to use up first. I figure if you fill an aquarium with Solarez and put a Z-axis table at the bottom, and a 2D UV laser on the top, you've got exactly the same thing for which others are paying thousands of dollars. I don't know how strong the Solarez would be in a stand-alone construction and I doubt that the manufacturer of Solarez intended it to be used in this manner, nor do I know how the stuff would react to a UV laser, and if it is practical from an elapsed time frame of reference. Again, I don't have the tech skills, nor even the need for such a device, but I think it's within the skill set of some of the more talented Instructable builders here. Just some random thoughts...
