2300lm Comment I think you mean lumens, not lumen's. No that answer is wrong Watts (energy usage) / Lumens (light output) 25 is equal to 200 35 is equal to 325 40 is equal to 450 60 is equal to 800 75 is equal to 1100 100 is equal to 1600 125 is equal to 2000 150 is equal to 2600 36 watts would be about 350 Lumens
No. -60 is 60 - 120, so they cannot be equal
The energy consumption of a modern Cree XP-G or XM-L based flashlight with 170 lumen output can be as low as 1.4 watts with 120 and more lumen per watt. The light output will be approximately equal to a 20 W tungsten incandescent light bulb or a 10 W halogen light.
60 is the only number that is equal to 60
60 - 90 equal = -30
The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.
This depends on the type of bulb and it's efficiency. Incandescent bulbs produce 700-900 lumens at 60 watts.
Lumen
No! 120 is equal to 60 x 2! It has nothing to do with 60%!
12060
60 plus 60 plus 60 equals 180 !
