Cutting off the top of a light bulb

Hello! I'm having a problem and have ruined quite a bit of incandescent light bulbs over it: I need to open the thing just below the thread and I have no idea how. I've tried doing it with an X-acto knife, but it never breaks evenly, and usually, there are tiny cracks along the edge. Anybody out there have experience doing this and any words of wisdom? Thanks in advance :)

How remove coating from lightbulb? Answered

Anyone have an idea what the inside of this light bulb is coated with, and how to remove it? It's not the usual white powdery coating. It's darker and a little clearer. I tried the salt method, but it did nothing.

How Bright is a 112 Lm/W LED? Answered

Hello, I am on a mission to find a very very bright led preferably in red. I have seen lots of bulbs with ranging prices but don't understand how bright they are. One led I have seen is the Luxeon Rebel LXM5-PD01 which comes in red and is 112 Lm/W, I understand that it means 112 lumens per watt but how bright actually is that? And what would be its power consumption? Thanks

350 Projector bulb power source?

Hey guys I recently salvaged the bulb from and InFocus LP1000B projector. I want to use this bulb as a light source but am not sure how to go about this because I do not know the voltage to run the bulb at or if the power to it needs to be limited somehow. From my research I believe it is a 350 watt Metal Halide bulb. Thanks for any help.

Light Bulb Lamps

Oh what to do with the light bulb now that you're basking in the efficient glow of your CFLs? Well, you could convert them into these light bulb lamps as Sergio Silva has done. It's a pretty sweet item with neodymium magnets holding them in place on an included acrylic plate with embedded bits of steel.However, the price tag is $650 for the set which is pretty flippin' ridiculous for what can be remade with scrap and $10 of materials, if that. To be fair, the light bulbs Silva makes are sturdier than the regular item, are all made by the original artist, and are limited to a run of 66. So you're buying some design-y street cred before they get knocked off and sold for one-tenth the price. Linkvia bbgadgets

Toshiba has stopped making incandescent bulbs after 120 years

Lighting has taken another step towards energy efficiency as Toshiba stopped making incandescent bulbs yesterday. It will now be focusing more on other lighting such as LEDs. This is all great news as incandescents wasted a lot of energy as heat instead of lighting. Now with a greater focus on the energy-efficient options we can expect to see quality and efficiency improve as prices come down.

Giant Hanging Light Bulb Lamp

I'm wanting to create a giant hanging light bulb lamp, similar to the ones I've uploaded, but I'm not really sure how I would go about doing it. I think I would make it out of plastic. So I would need to create a mold and then make two halves on a vacuum form, but I have no experience doing that. I'm not sure how I would make a mold of a giant light bulb, what materials to use and how to make it. I had thought about maybe cutting something out on a lathe but I don't have a lathe and it seems like it would have to be pretty big. I also thought about paper mache but I was afraid it might be too bumpy and light bulbs are smooth. Also once I have created the vacuum form plastic halves how I would attach them together with out having a large seam show.

Fish In A Light Bulb

So I was wondering do you think it would be possible to take an old ligth bulb hallow it out and use it as a fish bowl for a mini fish?  Im just not sure should I put a small plant in there and if so what kind of plant so maybe just a little air pump while Im gone.  Or would a small fish be fine if I put some rocks on the bottom and then just changed it once a month or so?  Or would it end up being every day do you think? Ethan PS I hope people dont bite my head off thinking Im a horrible person I just like the idea of having a fish in a light bulb I think it would look cool so Im asking before I do it and accidentally kill a fish...

Tesla illusion ideas / wireless light bulb help

So I was considering going as Nickola Tesla for Halloween and showcasing his ideas as sort of party tricks...like a Tesla turbine blade and whatnot. But seeing as he is primarily known for electricity work, I thought it would be cool if I could somehow come up with a way to make a lightbulb glow while holding it. I tossed around the idea of running a powersource to a conductive glove to power it and also of making a self contained powered bulb but not sure. Any ideas on how to make some sort of electrical phenomenon illusion? Thanks.

LED Conversion from battery to socket

I've found a few projects that touch on converting a standard light bulb to a LED configuration. But nothing that I have come across has a complete diagram for the conversion. I know that LED lights will last longer than most lamps and are much cheaper to run. But they cost upwards of +$20 each! Any help would be AWSOME!

Colored Lights- How do colored led lights work and what do they emit?

I'm doing an experiment by growing plants under colored led lights, so do led lights emit specifically one color. For example does a red led light emit only wavelengths of light that are red and no others. I want to make sure that only one color of light is existent to get accurate results. I hope this makes sense. Also if you know of any 1-colored high watt led lights please link them to me.
