SidewindR · May 19, 2005

hi
or 3mm for that matter
i'm looking for a bulb like on the Freedom
but in the 50kmcd to 100kmcd if that is possible
my Freedom actually comes darn close to some Luxeon lights i have and matches a couple in room light (dark then light up ceiling in my bedroom or bathroom enough to read on the bed)
what's out there and will and can they compete with the Lux and like 1 watters?
but take up only about
:
1/10 of wattage and or currents?
sorry if i don't explain it right lol

Maybe the 5mm ISP 100ma leds like the MJLEDs since they take a lower Vf to run at 20ma, then you have less wattage... They draw 100ma at typical voltages for whites... So feed them less voltage and you get ~20ma less wattage.

Or the new Nichia 50k(whatever it is)mcd ones?

hi hmm never heard of that one
but wow, that sounds right about,
i was thinking the normal 5mm white or yellow leds
something of that general current draw, but the brightest
you can buy, i know 26,000mcd is what i hear on Ebay from Chinese sellers, but you mentioned Nichia 50k? is that what's in the new Freedom lights? (2x as bright)

Yes I believe so. There is a group buy going on or was for the new Nichia leds. I don't know the actual rating but they are brigther than the 26k ones on ebay.

I don't understand quite what you're asking. You want a very dim light, to get around a dark room with? I had a thread about that a while back. The simplest thing to do is just replace the two CR2016 cells in your Freedom (or a cheap Photon II-style light) with a single CR2032. That will bring it down to about 1/10th of the normal brightness. With the Freedom, you can combine that with PWM dimming and probably get down to a barely perceptable glow.
