Were you at English Days in Michigan this year? You might have been the guy I talked to in the vendor barm about LEDS.
We use LEDS at work because they draw so little juice and have more than 10 times the life of standard electroilluminescent bulb.
The trouble with LEDS is you don't get the distance or "spot" out of them. The handlights they talked about use multiple LEDS then the cost is high. The bulbs used on the walking lights I assume are not LEDS. Mine has a little amber screw on cover and I have never looked to see what kind of bulb it is, I assumed it is a white bulb, not an LED.
My goal was to try to find an LED bright enough to use in a mining head, but as I found out LEDS just can't get distance out of them so useless in shining a tree. We also found out that a round top LED is brighter than a flat top, so I had Marl Manufacturing make me up some round top LEDS as we use them in Fiber Optics applications in dark rooms. We use green and amber LEDS for our film. The LEDS we use are bayonet base. They are 24vdc but can be illuminated with a 6, 10, or 12 volt battery up to the 24 volt, just that the lower volt batteries you don't get the brightnes out of them. Ihave an experimental white round top 24vdc LED here right now that is pretty bright I want to send you one to try, no cost, just as a favor, let me know if you can use it as a walking light on the side of battery. If you can I will gurantee it has very little draw on a battery and should last 10 years or better, even with high use. Send me your address I'll mail you a couple. If they work I'll give you the vendor name. address and cost! Be glad to help ya out!
