6 Xm-l light bar build

Great idea and awesome craftsmanship on the unit.

If you have the time, you might also want to experiment with a 5-unit design where the middle three emitters have larger reflectors (say 55-57mm) and the ones on each side have smaller reflectors and are angled out a few degrees. That will greatly enhance the throw down the center, as well as the flood off to the sides.

Also, when you do the beamshots, try a couple different shutter speeds, say from 2 sec to 6 seconds, I bet it will give you a better depiction of the beam.

Best application I have seen of XM-L technology outside the flashlight world.

Oh, almost forgot. You mentioned the optics being 26.5mm narrow; looks like they use aspherics. Have you tried it without the aspherics?

The board is one piece, so angling the side ones is not possible. The elliptcals give plenty of light to the side.

Leds are in strings of 3, so 5 is not logical. I am trying to make the light small, I do not want to use any larger optics.

The optics I am using are not aspherics.

Pics are F4.5, ISO 100, 6 seconds on a tripod. Canon T3i.

I’m thinking one of those would be an awesome compliment to a safari rack on my landcruiser, no bashing lights on low branches when green laning 8)

Beam shots with outer two optics swapped out for ellipticals.

Looks like a perfect mix of hotspot and spill now, very good! :bigsmile:
Would you say the exposure of the picture reflect the same amount of light your eyes were perceiving? If so that’s really a great offroad light for sure, the wait will be worth!

In the picture, was it still mounted on top of your DR Suzuki? I may be wrong, but light seems to be aimed slightly downward, and maybe it could result a bit more throw if aimed a little higher, don’t you?

Such an impressive build. One of those would fit perfect in the front of my car, that’s for sure.

The pictures are very close to what you actualy see.

Yes, these pics are taken with the light on the DRZ. I do have the light aimed down. Aiming it up did not gain any throw. It just took away the light righ inf ront of you.

Wow, that's friggin' amazing!

Ok, understand what you mean. There would be some personal preference in choosing aiming, depending on terrain and use. Now hurry up and finish them, you have customers waiting! :bigsmile:

Very nice!

Will it run on 24V as well?

9-24v input.

Circuit boards are in hand, leds and components are ordered. I am hoping to have these ready in 4-6 weeks.

I’m thinking the same thing, one should fit perfectly into the centre opening of my bumper!

Aluminum, boards and components. I drove them up to the assemblers Yesterday. I should have them back in a week. Time to start machining on the housings.

Looking good, did you consider the U2 binned emitters?

Nope. I will not go over 5000k for these. Any higher then that and it causes eye fatigue and no color rendering. Not good for fast driving. Maybe if they came out with a U2 neutral. I can get T6 neutrals, but they where not in stock and cost a lot more. With this much light you are probably not going to notice a few hundred lumens.

Cool, I thought it maybe due to the tint but that also explains why not the T6. Looking forward to seeing more :slight_smile:

glad to see updates on this one. I am interested in buying one.

Following with interest

I got the first batch of 165 boards back from assembly. They look great. First one tested good. Housing machining should start later this week.
