Replacement Lamps

[Spry]

Where can I find LED replacements for standard bayonet and screw in
lamps.

Immediate needs are:
4.8v 0.5a miniature screw with lens.
4.8v 0.5a miniature screw (no lens).

etc.

That's similar to a 3-battery flashlight, so some commercial items
exist, which contain an electronic controller and LED. The base
will be odd, though, and it's only good for 4.8VDC, not AC.

LED lamps often have built-in lens, there basically ARE no 4pi radiator LED lamps
that are exactly like incandescents.

Dialight makes some with an E10 screw base - their 586 series. The
lowest voltage they spec is 6 V DC; I don't know if they'll run on
lower voltages. Try

and scroll down, or
http://www.dialight.com/Assets%5CBrochures_And_Catalogs%5CIndication%5CMDEL586MSVIP001.pdf
for a wide-range input (6-36 V DC) version. Mouser and Digikey both
stock some Dialight stuff.

Chicago Miniature also has some based LEDs, but their website is broken.

APEM has some as well:

If these go in a flashlight, look at http://www.candlepowerforums.com .
Those people spend a serious amount of time thinking about flashlights.

Standard disclaimers apply: I don't get money or other consideration
from any companies mentioned.
