I am 99% positive they are Lisa2 optics, though I can’t figure out which specific model the “standard” throwy optic is. One of them out of my D18 measures 9.9mm diameter by 7.0mm height, not including pins.
The wide optic is, I believe, the 10997 model, or perhaps 11429. I ordered 6 from Hank to mix a little more flood in, but there is no part number or anything.
The two I ordered fit 219B with room to spare but still no LH351D. I suspect an XP-L HI, though not supported by ANY Lisa optics, would do better with this optic versus the stock one. I will try to compare a full set of stock optics VS a full set of FP13028_LISA2-M-PIN. The fit looks better even for the SST-20 to be honest…
Yes, and they powered the light without issue. I’ve been buying the flattops from Zebralight for years and they worked because the top protrudes past the label.
This is not a good choice. The current consumption from each battery is 15A (in turbo). This is the voltage drop with this load compared to Samsung 30Q.
It seems a good choice for his requirements which is longer, but slightly lower turbo output which heats up slower. Plus it has extra capacity to run longer at lower levels. Maybe he wants this?
With GA’s, the load on each battery will probably be less than 15A each.
I don’t think GA’s will hurt anything as long as you don’t care about measuring the max turbo lumens.
Yes, I agree it’s not a good choice if I’m bench racing for lumens. I’m curious how much lower the output would be with the GA’s. I’d love to see an output graph of with the GA to see what is given up in Turbo (which I’d rarely use aside from wowing people) in exchange for longer runtime at lower levels.
If you aren’t wowing people with turbo then don’t worry about using a GA. In reality I think the light is capable of pulling 15A per cell like komeko says but in my testing my light is only hitting 10K lumens briefly with a 30Q. So 15A is pretty much the upper limit with a 30Q using this light.
I did this for science but the results are so similar i’m not sure it’s helpful to anyone. The hotspot appears to be ever so slightly less defined and edge of spill slightly cleaner. I thought the efficiency might go up but it appears to produce more or less the same lumens with both optics. I still think XP-L HI might benefit from this larger LED opening but i’m only going to try 219B.
Datasheet has support for other small-ish die emitters: XPG2/3, 219B/C, Oslon Square, E21A, LH351B
I was fortunate enough to stock up then, and I have about six lights using them. I still have some to spare for future projects, but I still get weepy thinking about my favorite LED being discontinued.
I think I’ll turn on my 219B sw45k Emisar D4 to cheer myself up.
