Halogen to LED.?

Right now i'm working on photo spectrography, and using a halogen lamp because of the wavelength it outputs. The thing is, we are trying to make a more portable version of this, is there a type of LED or an array of them, that i could use for this? Take in mind that the LEDs have to output a wavelength very similar or equal to that of a halogen lamp.

Halogen Heater?

The one i feel s the most effective is halogen heater since they don't dehydrate the room like the others, but commercial heaters are ... how should I put this ???

Halogen flashlight mods

Heh...flashlights of death forum.....seems like just the place for this question. I've seen some vids online about using the halogen track light bulbs (mr16? something like that) in maglight mods. Anyone have any exprience in this? A couple of them can be ordered but they are expensive and custom built.....one of them is called a mag85 and there is another called "mac's torch". the guy that made mac's torch (i'm assuming mac) made a video in which he put down a piece of news paper and set it on fire with this light! I believe he was using a special order 100 watt halogen in that one. Now you may see why this question seemed appropriate for the "flashlights of death" part of the forum lol. Nice meeting you all and I'm always tinkering with things to bad I wasn't taking pictures but I will now!

How to run a mini halogen light from the mains? Answered

Hi all, I am working on a project and need to run a mini (35mm) halogen globe from the mains.  I live in Australia and our  mains from off 24v.   If I try and run the halogen it works ok but soon heats-up a lot.  I'm assuming that I need a transformer to reduce the voltage or amperage but cant find anything on the net!  I want to run the lamp that I am building direct from the AC socket.  Does anyone have any solutions?  I have also looked at 12v LED ones as well and thought that this might be the best path to go down.   Thanks, Marcus

Hack Needed: Rechargeable Halogen Spotlight

Greetings all, I'm in need of a hack to replace the lead acid battery in a rechargeable halogen spotlight purchased at a local store. The spotlight came with a AC recharger but 15 charge time hours returns only approximately twenty minutes of usable light. I'd much like to replace the power source with something of a longer duration than the current one third of an hour. As much interested in simply rewiring the device to work from my car's AC outlet if possible. Mind I only have a few dollars invested in this device still I'd like to see if a replacement power source is worth the effort.

why do halogen lights keep blowing? Really scared of fire!

I live in a rented attic flat and just before Christmas four of the ceiling halogen spot lights in my hall and livingroom blew.  I called the landlord (he is an electrician) and he replaced them - then charged me £50!  Two days later the same lights blew again.  There seems to be condensation or something around a couple of the bulbs. (They are sunk in the ceiling.) The next day I went away for two weeks for Christmas, came back yesterday and this morning there was a 'pop' noise and all the five lights in my bedroom blew. (I hadn't just turned them on. They were already on.)  I can't locate the fuse box and I am worried about an electrical fault causing a fire.  It is a new flat (five years old, and the landlord did all the wiring - he is an electrical contractor.) I have to be out all day tomorrow, leaving my little dog there, and I am scared there will be a fire.  I am going to speak to him tomorrow and try to get him to come and sort this out tomorrow night when I get in, but it took ages to get my landlord to come and sort the last thing out, I am living in semi-darkness, and I can't afford to pay hundreds of £ every time the bulbs go.  I have only lived there three months.  What should I do?  Is it safe? I would feel better if I could turn everything off at the mains before going out tomorrow, but I don't know where the thing is to do this - and I don't want to meddle with stuff I know nothing about.

However, could I spot weld with it, I mean really thin pieces of metal, not to mention what else could I do with it.

Question about a flyback's polarity Answered

Hello, I am confused with this flyback transformer I have. I have a pulsed DC input on the primary coil (pulses from 0 to 15V) and that creates high voltage in the secondary coil. When I connect that input in the opposite direction (wrong polarity) I don't get high voltage any more. The possible explanation for this is that the primary coil has a diode in series with it. Now, I'm confused by this because I tested if there actually Was a diode in there (by connecting a DC supply and a DC motor, in series with the coil) and the motor always works! (also tested with a halogen light) I put the coil in series with the motor to test if there is a diode inside. If there would be one inside, the motor should not work in one of the two cases, when I switch the pins of the primary coil. So, as the results of the test tell me: there is no diode in series with the primary coil. could it be possible that there is a diode in parallel with the primary coil? If that's not possible, how come the flyback is not working when I connect the polarity incorrectly? Could someone please help me out with this? Thanks, Electorials

cheap LED sources

Hey everybody, I've been looking for a good source for cheap LEDs for a project I'm working on. I want to replace 14 different 60W halogen bulbs with home-built LED lights. The reason for home-built is that the halogens burn out like crazy, but the light fixture looks nice, and isn't going to be replaced. The halogens put out an estimated 500-700 lumens (from the google research I did)So.... I'm looking for the best deal for white leds per lumen. the best deal I've found so far is:http://www.phenoptix.co.uk/Ultra_Bright_White_SUPERFLUX_LEDs_3000mcd_p/whi-flux-3000.htmat .021cents/lumen from the brightness calculator http://led.linear1.org/lumen.wizbut considering the quantity I want.... there's not even enough room to fit those LEDs on the fixture (due to the large case size)or if I buy 1000 of them (about the quantity I'm looking for) I'd be getting a slightly better deal, but still coming in at $120, not to mention they still don't fit. The physical space for the leds is a cylinder with a diameter of about 30mm and a height of about 70mm. Any Ideas/suggestions for cheap white LEDs?Thanks!-Zaen

( I might have as much as 60 - 90 watts to work with, as I've swichted all the other lights on the bike to LEDs so my power usage is down from stock) It would have to have a running light ... and a "bright" light. I have no experience with LEDs, and A minimal amount with electronics. Any help would be apreciated.... I have no idea where to start with this... Requirements: Waterproof Super Bright (brighter than a 55w halogen bulb, would like to be as bright at possible) dim and bright mode Able to run in 0 - 130 degrees ferenheight evironment(spelling)
