Does anyone have any info on these new Kings for different models (3 vs 4 vs 5 …) how much current they are pulling high vs low mode? FT numbers are hopeless.
Would lower voltage LiFePO4 work for 3-5 LED models?
Don’t remember, seems all 4 cells are in parallel so boost circuit? So may pull more current to compensate for lower V?
I agree, this might be the easiest host thusfar for a retard light! No messing with battery configuration, it is already 2S3P, reflow 12 XHP50's (XHP70's might not fit behind the reflector) on Sinkpads, or just buy them on 16mm copper boards from Kaidomain (I bet that those boards will work fine at the current the leds will get individually), solder them on a copper plate, do not bother with a driver, just wire the batteries (LG HE2's) through to the leds, bypass all tail springs with 18AWG wire, replace the switch with one of these: , and I bet you have 30+ amps with 25 klumen or more. Total costs 150 dollar?
As a SRK fan i am interested in those too, i use SRK alot arround my house and as an offhand fl when camping/hunting… should be definately an interesting review to read
I like how you are thinking here It is always good to know how to build the cheapest “retard” level light
150$ for 25k lumens sounds like a great plan.
I had checked out the TR-J20 as a host before but this one is cheaper & have 18650 in 2S3P, instead of the 32650’s in the TR-J20.
I would like to see this at my local Harbor Freight for $3 with coupon, similar to their 27-LED portable work light, which is actually quite nice already:
Huh? There is no big vendor that will sell the triple spacer heat sinks, for sure. What specific light do you want it for? Maybe someone has had experience with retro-fitting one of RMM’s - I know I have. I sanded down an S2 spacer to fit a S3 light for example. All depends on dimensions, etc.
Was looking around for the Nitecore HC65. It's out of stock on the "BG" site. On a lark I checked Fasttech. They showed a similar price, but then a coupon code of "MAP" popped up. I got the light for $49.95. That seems to be the cheapest price around, AFAIK...
