If its about cost per lumens then a single xhp70.2 will massively save 2/3 of the most expensive component. reaching ~6-7k lumens with mt07 haikelight driver with a good bin xhp70.2. The larger reflector will increase effective light OTF efficiency to exceed 9k lumens 3xsmall reflector output and will out throw it…
Using 3 high end leds 6k lumens specification for 9k lumens is pure waste. The potential output can easily be ramp up by choosing a lower resistor value for boost mode with not much change in manufacturing cost. Boost mode allows Heatsinking cost from extended runtime to be avoided by a thermal resistor which is already pretty common.
The lowest cost will be a direct driven 16v 4 cells in series connected to 3 xhp70.2 led without a driver.That will give upwards of ~15k lumens direct driven with no efficiency loss.
My point is The cost has already been sunk so its not about cost consideration in this case but to avoid wasting good leds- Finish your meal kids. Make it 20k lumens by including a 20klumens boost mode in the light option at the same production cost and see the Q list fill up instantly. :+1:
Are there any other power house flashlights in the club buying list like this at a decent price? I really like the XHP line of led’s, especially using multiples in a build. If some one can point me in the direction of a 10k+ lumen with 6000k or higher color, I would be extremely grateful.
For those that are not familiar with Utorch, they are a new company and currently have 2 models on the market. The UT-01 and UT-02. They are both very close copies of another brand. Right down to the same driver boards which still has the other companies name on them.
Take a look at the Utorch UT-01 here. See the Utorch brand on the outside and the “M” brand on the inside?
