No reviews yet that I can see, its meant to start shipping end of this month.
You’d think 300 lumens per watt isn’t possible but this review + my own experience show its not far off - HaikeLite MT03 review with measurements (3x XHP70, 4x 18650)
Scroll down and theres a blue box with test results. High mode was measured at 3470 lumens with no stepdown and runtime to 10% was 4hr 10min. Batteries are 3500mah so 51.8 watts between the 4.
51.8 / 4 hours (rounded) = 12.95 watts
3470 / 12.95 = 267.95 lumens per watt
It states batteries ran down to 10% so if we adjust the wattage used down by 10% it actually works out to 297.85 lumens per watt.
I don’t see any change in brightness when I run mine on high and it doesn’t really heat up as its been around 10 degrees © at night when I’m out so I don’t think it has any need to step down, the manual only mentions this happening on turbo. I don’t think Haikelites claimed runtime is far off as my runtime down to 60% above is also based on 3000mah batteries as well. So if Olights specs are correct then yeah I’d say its pretty inefficient by comparison.
Edit : thats not meant to be a copyright logo, I put a c in brackets and it did that lol
