I need a green light bulb like this

Click For Summary
SUMMARY

The discussion centers on sourcing a green light bulb compatible with a 2.5V 0.3A incandescent bulb base. Participants suggest various solutions, including purchasing green compact fluorescent bulbs from Home Depot and using LED alternatives for efficiency. Colorizing existing bulbs with paint or markers is also mentioned, though these methods are not durable. The conversation highlights the challenges of finding small bulbs and the potential of using stage lighting gels for color effects.

PREREQUISITES
  • Understanding of incandescent bulb specifications (e.g., voltage and amperage)
  • Familiarity with LED technology and its advantages over incandescent bulbs
  • Knowledge of bulb bases and compatibility
  • Basic skills in DIY modifications for lighting solutions
NEXT STEPS
  • Research LED bulb options for 2.5V applications
  • Explore color gel options for stage lighting to modify existing bulbs
  • Investigate compact fluorescent bulb specifications at Home Depot
  • Learn about the differences between incandescent, LED, and fluorescent lighting technologies
USEFUL FOR

Anyone seeking to create custom lighting solutions, including DIY enthusiasts, event planners, and individuals interested in energy-efficient lighting options.

So I have a hilarious idea waiting to be exploded onto the world and I need a green light bulb. I have this bulb

t8suae.jpg


that is a 2.5V 0.3A incandescent bulb. I'm not entirely sure I know how to determine the type of base, but I could probably grab a micrometer and some diagrams and figure it out. Does anyone know where I could buy a green version of this bulb? How do they even make green versions of bulbs? Just colorizing the glass? Can something be sprayed over to make this white bulb a green one?

IDEAS ARE HAPPENING!

Do these come in compact flourescent versions as well? This one is in a light fixture that's powered by AA batteries and I'd love a bulb that's more efficient :)

I WUV U PF! DISCUSS!

'swhat I did for Christmas one year. I had strands of white lights and I wanted blue lights. So I used a magic marker on them. It's OK for a while. Won't stand up to much weathering. How long does your idea need to last?
 
There's like this new super crazy invention I've been heard about recently that's sort of like a light bulb but not. Its like really efficient, cheap, and comes in a lot of different colors. I think its called like a LED or something.
 
Sigh...they're called "lamps". You want bulbs? Go to a garden store.

It's 12 volt but green. And it's has one of those LED thingies.

They have green compact flourescents at Home Depot. They are expensive.

You could also do it the way that I did to get orange, red and blue for a fake fireplace. Talk to a band at your local bar. They're bound to have damaged or excess pieces of the gels that they use for their stage lights. You'll get the things for free, and they're guaranteed to not melt under 1,000 W at point-blank range.
 
Green paint. Or a marker.

Pengwino, you can't make a green light unless you get a green light from the government.

I think it's Rule 22. o:)

Green light bulbs.

I should have mentioned that it needs to go into the same base as the light bulb in the picture :P. That's the problem I'm having, it seems hard enough to find light bulbs that small in the first place.

Although you don't indicate the scale, that looks like a run-of-the-mill flashlight bulb to me. Most are pointy, but not all. The round ones that I've run across were usually on the back end of hand lanterns, under a red shield, and were flasher units. Not always, though.
You should be able to find them in your local hardware store in the battery display. (At least, that's where we Canucks stash them.) They come in regular or frosted, but not coloured.

You can also use LED lights for this. They will work well for you
