LED panel lighting redux

[NormB]

This works for me, you might try it.

Red lighting preserves night vision. Never could figure out a rationale for GREEN panel lighting.

I bought a small bottle of Vitrea 100 glass paint and some Eiko 6S6/30V bulbs (about $8 and $10, respectively), but didn't like the paint finish. Might've worked, but went ahead and bought some LED lamps of the 194 base variety.

These come apart very easily. I broke the glass capsule/bulb, scraped and tinned the filiment wire leads and reattached them to the circuit board for the LEDs (non-polarized).

I then used some tape and five-minute epoxy to "pot" the base/lens unit, coated the base with a little dielectric grease and VOILA!

One more to go.

I may be mistaken, but I thought green was better for night vision.

Tagged for later. I'm curious about your solution.

Maybe. I seemed to recall some of my neurophysiology study from Kandel and Schwartz some decades ago so I dug around a bit.

Jury's out.

I prefer red. and the light coming through the faded dyes on the bulbs was closer to yellow-white anyway.

YMMV.

Is there no direct replacement LED bulb for this application yet?

Red is better at not disturbing your night vision. The human eye is much more sensitive to green than red.

Imagine having green tail lights on vehicles?

I haven't seen colored versions of these in LED. I used the white ones in this post.

Thanks!

These will fit.

I bought some of these size LEDs in 120v AC type as replacements for 4W night light incandescent bulbs (which were more expensive).

I just plugged one in my genset and it fits, and works (surprisingly, as it's rated 120VAC not DC voltage).

Poke around, you might find them cheaper.

Seriously, a set of four with S&H is around $28. Couldn't find red though.
