I assume it’s 40W or is that something I have to ask the manufacturer? Where I’m coming from is I’m curious how that would compare with the Fireflylite X1S 707A 5000K 95CRI. I assume the higher CRI would make it less bright than the TS22 which is a lower CRI?
XHP 70.2 = 220 lumens/watt
So, 4500 lumens/220 = 20,45W luminous energy.
Let’s say it uses 15 amps at start. So, the consumed power is 15a x 4.2v = 63W
For the same light, but hich CRI:
3000 lumens max and 15 amps at start.
So you have the same power consumed but 33% less output.
From koef3s LED test:
Looks like 6.8A and 6.3V, so approx. 43W. Since koef tested the 4000K model, and Wurkkos uses either 5000K or 6000K, my guess is it uses a 6A driver (37W). So, yeah, pretty much something betwen 35 and 40W, most likely.
Ofc, the flux bin of the LED affects this a lot, so does the CCT. Forward voltage fluctuates between individual LEDs as well.
I think I measured SP33 driver giving 5.7A on turbo. Been a long time since I measured it, so can’t be 100% sure.
They run probably 6 A at 6 volts for the driver output. Input at the battery is around 8-9 amps. The TS23 i tested did around that. The R9050 version will have lower output but similar power consumption
An XHP70.2 at 4.2V?
And still with 220 l/w at 4500 lumens?
It’s not wrong to assume 4.2v, as the reviews often measure the tailcap current, not the led input, which has been boosted by the driver to 6v. The TS22 high CRI review made by 1lumen was the source I used for this data, take a look there.
The current on the led will be less than 15a, in this case.
The lumens per watt will be less, as you said. At 5A, the efficacy will drop to about 130 lumens per watt, so the power input will be more or less 34w on the LED.
