KD has a new 5 led drop-in rated at 1800lm max but there is no information as always. As I made a search immediately, there seems to have been been a WF-1800 5xled flashlight already but rated at a lower output. This might be the one with R5 leds, I thought. Now, does anyone have any information about this 1800lm drop-in? It says 5.6cm diameter but WF-500 compatible drop-in's have a 52mm diameter. Could this be the same diameter or is there another body fro this new drop-in to go in?
I have been waiting to buy a 5xR2 drop in for my TR-1200 body for a while but this one brought everything to the scratch.
5 properly driven R5 at 1,4A each would really ask alot from two 18650. It is doable but i can't see the point now that XM-L is available and can accomplish the same with 3 leds and a bit less total current maybe even heat. Unless you want a throwy light with R2?
Individually driven leds those are at their most efficient region must give a more close hit to thier claims. I mean not 1800lm but something like 700mA driven to each led should give about 1400-1500lm easily. Of course a well driven XM-L can win the race but I bet even it (at a x3 configuration) can struggle against a 5 led one.
But the thing is, there is no information about this drop-in, or if it can fit in a WF-500.
In my opinion it is a bit pricey to find out the hard way.
1800 real lumens is going into good HID territory. I wonder why are still that expensive with such low bulb lifetime (compared to common life expectany of leds)
