Ledil Crystal, coming soon

Thanks for your expert opinion OL. I just revisited my 42mm TIR and compared it again to the FT 20mm. As others just pointed out, the thickness of the plastic definitely has a huge impact on cutting lumens WAY down. Looking at the mechanical drawings of the C12916_CRYSTAL-RS, there is an 8.2mm cavity above the emitter mounting location, so the emitter must still penetrate 19.2mm of plastic before photons escape through the font of the lens. Unless Ledil came up with an optically superior transparent plastic, the Crystal is probably intended for aesthetics for indoor lighting; as you had pointed out.

The Idea was to mount 32 of these in a DIY light bar, with holes drilled though 50” x 5” black plexi sheet to center them. Then I wouldnt have to have a clear plexi lens over the array (that would cut lumens). Oh well, I’ll give one a try once they’re available and report back.

Id love to run 16 HD2010 reflectors + 16 Ledil Boom reflectors. To bad we cant find a source for the 2010’s. The DX SST90 reflector is still a contender, but Id need to stagger them in a small arc to make the best use of 16 beams from that section of the array and that still might be a bit to focused to be of any use while wheel’in.

That DX SST90 reflector is the best MTG-2 reflector I’ve come across for creating a hot spot.

Its supposed to be killer with the XML as well. I wonder if it would focus to tight a beam to be useful for an offroad pickup. Do you have any ideas? There would be 16 in the array. I could probably shim them slightly left and right to cast an arc rather than just one mega bright useless culminated spot, but that still might not be enough.

I wonder if that DX reflector does a better job focusing the MT-G2 into a hot spot than the Solarforce M8 hybrid reflector, or the Solarforce S2200 OP reflector, still trying to find a reflector from a S1100 for the mirror finish to use in my S2200. Solarforce won’t sell an S1100 reflector as a stand alone unit.

I’ll gladly try this DX one though, even if it’s smaller. (which it is) JB Weld stick is wonderful for making adapters. :wink:

Its $160 for the DX reflectors so Id like to know more about them before I buy. Thanks for the JB Weld stick idea. I was thinking about using pvc tube for a support ring with JB weld epoxy, but the stick sounds even better.

The stick is easy, comes in a roll like a jelly roll, cut off an approximate amount and knead it to mix the 2 parts…since it stays like a putty it’s pretty easy to put in place and shape, a wet finger helps smooth it down and keeps it from sticking. I like using the Water Weld, it’s white though. But it sets up fast. It’s my next go-to in a light over the expensive Arctic Alumina Thermal Compound, which I like to use when potting.

How well does it fit a Mag D?

DBCstm:

I havent seen the Water Weld yet. You use that to fujic the stars? lol. Ive been using the super low viscosity super glue (with high clamping pressures till it dries) with great success. Heat transfers far better than fujic and it sets up in about a minute or less. I buy MX3 tubes on ebay when they come up for sale and its more than adequate when there are high clamping forces to push the reflector against the star.

Did you ever try out your DX SST90 reflector with XML?

Its far to large.

It’s 73mm in diameter. It doesn’t fit a mag.

Nope, I use either Arctic Alumina Thermal Adhesive or Arctic Alumina Thermal Compound depends on whether I feel like it’ll be getting changed or not. If I’m putting the copper star in a copper pill, I re-flow it in with Kester solder paste.

Sometimes I pot a driver that has a lot of chips on it, and especially when I’ve stacked chips on the battery side of the board. When I do that, I usually put a solid brass rod on the positive pad of the driver so that I don’t have to worry about spring compression causing a short on the stack of chips. Potting the soldered legs of the chips helps me feel better about the short possibilities too.

This is the kind of stuff I worry about when I’ve got 22 chips on a Qlite. :wink:

So what’re the best reflectors for a Mag D?

For MT-G2, the stock Mag LED reflector. For XM-L, there’s two reflectors from CNQG. Here and Here. Believe it or not, the shallow one will produce a tighter spot, with a smaller spill ring.

They both have to be "fitted" into the head. Nothing aftermarket fits exactly.

The shallow CNG will out throw the rebel mag reflector with XML?

The spot is about a toss up, but it's a smoother transition from spot out, unlike the LED maglite reflector. I like it better. I don't have lux ratings between the two, but by eye, I think they throw just about the same.

Lux readings between the shallow CNQG and deep CNQG show the shallow one a little higher reading.

You can buy Maglite parts at Zbattery. LED reflectors are here.

Thanks OL. Im torn with what reflectors to use with my light bar. I was thinking about going with the Ledli Booms or C8’s for the midrange/flood but not sure what to use for the spots. Do you have any suggestions? I like the DX SST90 but dont own one to compare. If the spot is to tight, it will be useless.

The idea is to have 16 mid-flood and 16 spot. But if there is enough spill, I could go with 32 spots. The investment is starting to add up so I need to try and get it right the first time.

Thanks OL, I think I’ll order a couple of the cnqg bits.

Well, the Booms will be floody enough, maybe a combination of them and C8 reflectors. I would think the C8 would be enough for spot, but it depends on how far you want to reach out. With the height/size differences, maybe it would be worth it to stray away from the SST-90 reflector and go with the stock Mag or one of the CNQG. I need to look back through all the threads I did, (OMG) and I know there are beam shots of both the shallow and the deeper CNQG reflectors. If you really need throw, then possibly 4 or 8 of the Mag LED, and the rest a combo of C8 and Boom. I would think you might not meed more than 4 to 6 of the Boom, depending on how far spaced everything is.

EDIT: Here's a couple shots of the CNQG deep reflector.

LOL! I was actually back tracking through all of your threads last night trying to accomplish the same thing. Thank you for your help. I need the farthest realistically useable throw possible. So the spot cant be to tight or it will be to narrow to be useful. I already have 2 x 100W HID wide angle floods in the bumper (18k lumens). I cant cycle the floods to often because they are HID. So the idea is to have an array that will provide reasonable flood with as far reaching spot that I can cycle on and off if necessary.

The heatsink is 2pcs 25” x 5” and 20 lbs each. So it will likely be cobbled as one 50” x 5” and weigh 40 lbs. Spacing out the DX SST90 73mm reflector, 16 of them will fit if necessary and I could probably stuff 16 Booms or maybe C8’s in-between the curves of the larger reflectors: Spots at the upper edge, smaller reflectors at the lower edge. I like your idea of C8 reflectors, and 16 of them should easily provide more than enough overlapping flood. Now I just need to figure out what should be used for the spots.
