Finally Pushing Super Bright Luxeon w/ 2 AA 3.6\'s

:
Hi i finally got a Luxeon 1 WATT batwing going
at FULL capacity that is it'd getting hot tho not very
just enough to burn /ubbthreads/images/graemlins/smile.gif om 2 AA SAFS 3.6 volt lithiums
right now it's been running with these 2 batteries
(using built in leads on both ends to tie them together to the LED) for 37 hours and they are beautifully bright
i just ordered a bunch of these batteries but they are a bit expensive for these experiments. i also made a sunrise sunset switch.. i figure 10 hours at night..good for nearly a week of Luxeon lighting front porch in relative good bath..
no expert here but it looks to the idea just as bright as my 12volt micropuck 1 watter on the porch and surrounding area , even lighting up the trees around , anyway not bad for straight out from battery no resisters just a primitive and LONG
:
runtime!

37 hours straight on 2 aa 3.6 v safs even with the cells in paralell
seems incredible

350 ma for 37 hours = 12 amp hours = I do not think so

200 ma for 37 hours = 7.4 amp hours = still a problem
so I guess it comes down to what you call bright

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3.6\'s

hi anyone else want to try the tests?
willing to send someone a couple cells for free
who has a straight 1 watt bulb to wrap around a couple of these in parallel 3.6v @ 2.25ampsx2
or if you have them let me know
i need more data

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3.6\'s

well day 4 and still shining 1 watt at half bright
lighting up surroundings , on my porch
2 3.6 AA SAFS
should not be possible but it's put out about 20 times the same energy as 2 aa aklalines

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

What do you mean half bright? Did you measure the brightness with a lightmeter and/or the current with a DMM?

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

I have several loose 1 watt luxeons
I will run 2 of the cells dead for you

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

hi yes with eyes only. no light meter here
just email me your address where you want the batteries sent

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

Hi to all i send the batteries too
let me know if you got them and any results so far or experiments as to set up for 1 WATT Luxeons and runtimes

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

I got the batteries I will connect them to a luxeon soon

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

Make sure to recycle those batteries (lithium thionyl chloride) properly when you're done with them. The chemicals inside are very poisonous and tossing them in the trash is bad news.

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

I have soldered two of the cells in parallel
I put a heat sink on a q3jw star after 2 hours it is pulling 175 ma

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

now I measure about 169 ma

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

now the led is pulling 173 ma

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

now it is pulling 170 ma

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

now 162 ma

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

Watching...is the light super bright? I wouldn't think so if the light is only drawing ~160mA. /ubbthreads/images/graemlins/popcorn.gif

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

now 90 ma

seems pretty bright to me 1t 160 ma
it is a naked led with no optic or anything

Re: Finally Pushing Super Bright Luxeon w/ 2 AA 3

So how long has it been?
