The led's vf is around 3 not 12. So it would be 150w/3 volts=50 amps/30 leds=1.66 amps per led. Naturally this doesn't mean anything because they say the LEDs are 5 watts but they do not say they drive them to a full 5 watts.
so if it’s 1.66 amps per led thats approx +400 lumens per led?
400 x 30 leds = 12000 lumens ? the main heder says 12000lumens nut the detailed description says only 9k
of course these are chinese lumens hence my desire to really know whats the true output.
Well, not really. The problem is they say the LED is a 5w led. They do not say that they drive it to a full 5 watts. Even if it was driven to a full 5 watts then 9000 lumens is a better estimate because the lenses block a large amount of the light.
I'm not sure why you're figuring out how much it draws from the cars battery unless you want to figure out runtime.
If the driver is 100% efficient then 150W /30 = 5W = ~3.3V x 1.5A = a fully driven led and the claim would be reasonable. This is not likely but at least they aren’t claiming more than is even theoretically possible. Should be a very bright ( and hot) light. I don’t see much in the way of fins for cooling that much heat. Can’t really predict output due to lack of driver specs. I notice they demonstrate it mounted on a tractor. A lot of money for guesswork.
ok. your inputs are noted and appreciated. just wanted some confirmation from the more informed if the 9k lumen output
is realistic. im still looking for a CC led automotive driver to pair with this light. i was in contact with a driver maker at CPF
but the sites kaput at the moment.
looked at some light bars from visionx and rigid but those are just way off the budget.
bigtoy302 is doing a xm-l bar but i think its still not available for the market.
