I've had both kinds in different formats and I personally prefer a single LED over multiple ones especially since I prefer lights with middle hotspots over floodlights (multiple leds tend to be more floody). There are some expensive quality lights out there that have 3 leds and the same with the single one's. I think the single one's can be more efficient though for the most part. The best ones I've ever had were single, but I'm unenlightened concerning the higher quality multiple led flashlights and drop in's.
the Efficiency is better with multiple leds, more lumens for less heat, the D4V2 (hardly cheap!) uses 4 main emitters, the Lumintop FW21 Pro uses 3 emitters (10,000 lumens!).
you can`t go on LED count as a function of quality, that would be like saying all red cars are fast
Sorry, but this is completely wrong. It depends on the light in question on a case by case basis. And also depends on what the light is intended to be used for.
Surely many LEDs offer over 1000 lumens. Even to ANSI FL1 standard, not just at the LED.Flash forward to today LEDs are brighter and more efficient. Of course, short of using a high-power COB LED, you're probably not going to exceed the 1000 lumens mark with a single LED.
Wow - first post; :welcome:

A well driven Cree XP-L or XM-L2 will do this. Plus more modern offerings like the XHP35, 50 and 70. Or even the large MT-G2. The Luminus SST-40 and SBT90.2 will also easily exceed 1000 lumens. In fact I think the SBT90.2 is more like 5000+ lumens if driven hard enough.
Personally I prefer an array of high-performance emitters rather than one central one; flood is really my thing & I have less use for throw.
Thanks, I need to not post right after waking up, so as to allow some time for my slow, lumbering, earthy fleshy mind to catch up to my nimble non-earthly spirit.This is CPF. [emoji16]
It depends. You need to take into account efficiency of each l.e.d. at different drive currents, the circuitry running the l.e.d.s, and losses from reflectors, optics, and lenses. Does one light have an electronic switch with a parasitic circuit and another doesn't? All these things will factor into the equation.
Indeed - thus 'the brightest' or 'longest throwing' or 'longest runtime' should not be the only considerations when shopping since there tend to be a multitude of factors such as size, price, fuel source, formfactor, etc.I suggest getting a light based on whether you need flood or throw more and which light gives you the longest runtime on the brightness settings you use the most. Efficiency doesn't mean squat if the light doesn't reach where you need it to (far enough or a wide enough beam).
