But 10 lumens flashlight is well enough for your hiking, camping, backpacking activities. What are your views assessments on the M7 torch?

In energy-efficient bulbs, the number of wattages lowers to achieve the same number of lumens. Use the luxmeter to identify the brightest point of the beam pattern and record the highest indicated value. LED Night Construction Lighting – Requirement and Guide, 100 lumens in Incandescent bulbs give 20-25 watts. And if the ceiling is 8-feet high, you may need an additional 10 lumens per square feet. 10-30 lumens:  this amount of lumens produces brightness like a candle.
