7500 lumens rating is pushing it. Maybe it's a higher bin? In djozz's test, his limit was 20 amps, but I don't see the LED peaking much above 5500 lumens at the max.
Yeah, Texas_Ace says the SBT-90.2 in the GT90 (uses similar FET driver and 8 x 18650 cells) maxes out at a bit over 5000 lumen. Lumintop also did an exaggerated lumen spec of 7000. I guess it’s just marketing.
I'd add a 10-15% for bump from our calibrated lumens to "manufacturer's" lumens. But still interesting a higher bin SBT90.2 should go from 5,000 to 7,074 based on scaling up the bin from SA to UB. SA to UB should increase lumens by 41.47%.
7500 lumens is exaggerated. So far, Hank sourced the highest bin of the SBT90.2 I’ve seen, which is still the 3rd lowest bin and doesn’t even make 5,000 lumens in a host without de-lidding. I don’t believe any bin above that is available on the market.
I think it would be a great host for white Flat or old style xp-g2 dedomed. You always can do a rebuild when you want to sell it. I hope I get a good reflektor without any issues.
Good news: Successfully ordered! 3 o’clock in the morning, I woke up after having a nice dream about violating my strict vegan diet, then I read a commentary on the Letter to the Hebrews, then I logged onto the BG webpage, I tried again, but the pre-order button was still greyed out, so I found my cart, I cleared the two items that I was unable to order, then I tried again, and this time I was successful!
