i need help creating a fixed led light.

[Schieltz]

i'm looking to make a fixed led light that is as bright as possible, without burning out the led of course.

the problem is, i've never made a light fixture before, and trying to process all the information on this website is making my head explode.

i have one of the fenix L1D CE flashlights with the Q5 cree bulb. i love this bulb, is it the brightest led available? or just the brightest in a small enough form to fit in a flashlight?

size and power is not my concern. i just want to make the brightest light i can. this would be an overhead light. anyone have any suggestions?

and are new led bulbs still resistant to vibrations? while the light wont be getting hit with anything, the structure it's mounted to would be moving and vibration would be introduced.

Welcome to CPF!
To answer your question, as far as I know, the Q5 is not the brightest Emitter out there. (Bulb is for incandescents, Emitter for LED's.) Are you looking for a single LED or Multi-LED source? As featured in the new UA2 and UB2 from Surefire, Seoul SemiConductor is coming out with a 6-Die emitter capable of 400+ lumens, all from a single LED. You'd have to wait for that one. If you're willing to go a multi-led route, I've always liked XR-E's (from cree) since they've been available for fixed lighting. My theater uses them for booth lighting, and once they were installed, we've never needed anything else. It would help if you could state the purpose for this installation, and what type of beam you're looking for. (I.E. Spot/Flood/Combo of the two.)

In any case, I hope this helps, and :welcome:

Quite bright here.

And here. These you can actually buy.

Otherwise R2 Crees from cutter are the brightest "normal" LEDs.

thanks for the info guys. this really helps.

basically i'm looking to create overhead lighting, but the ceiling is 3 stories high. i currently work in an industrial setting. and while most of our overhead lights are fairly reliable when mounted to our overhead cranes have a tendancy to burn out very easily because of the vibrations from traveling the rails all day.

now maybe led's arent bright enough for this purpose yet. but if my little flashlight on 1aa battery can come close, i figure it's worth a shot to try and find out.

to answer your question on single or multiple led, i have no preference. i have plenty of room to work with so i just need brightness. wether that comes from one led or 6 really doesnt matter. and in the long run, if it looks promising this wouldnt be just one light lighting up a whole room, it there are light fixtures aproximately every 10 feet or so on the ceiling. so combined they just need to get the job done.

the other benefit to a led would be the color. currently all our lights, have a deep yellow tinge to them. would be nice to get a whiter light installed.

Realistically, since this is somewhat of a one off, I would go with something already built up that is as off the shelf as possible. You should be able to find something in here that will suit your needs:

I don't think they have the latest and greatest LED technology, but since reliable is your goal, this is probably your best bet.
