What are the models of ultra high brightness LED on flashlights?

Answer:

Multi core - currently the main MCE, Quad, 10W, known as the highest brightness 900-1000 lumens, but the drive current is large, but the heat also much larger than the single core LED, light is not good, the floodlight is larger, the power consumption is also great. The general need to drive 2-3 lithium battery in order to reach the ideal effect.
Other LED, such as quad core P7, LED, SSC produced, 900 lumens, in the flashlight on the application of quite a lot, there are some other LED, not one by one to repeat it.
Lumens LED now more fire is the new SST50 and SST90, known as the 1500 and 2200 lumens, need a current of 5A and 9A, 3 and 6 lithium battery driven is good, the price is very expensive, one hundred yuan and more than 300 yuan respectively. Not much is used now.
At present, more LED used on flashlights are mainly two kinds of CREE and lumens.
CREE's main models are: single core -Q5, R5, these two are currently the most commonly used, the other although there are, but the size is not large, many models have been eliminated or discontinued. Q5 is the highest brightness of about 230 lumens, converging slightly better, but the heat is not small, the new R5 XPG floodlight is slightly larger than the Q5 XRE, but higher brightness, luminous flux of 350 lumens Q5 higher than one half, and high brightness driving, low fever, high light efficiency. Now more and more with the torch in hand.
