2wled lights equal to how many w incandescent?
Plus incandescent lamp is 360 degrees light, some light loss, so in order to achieve 140lm effective luminous flux
Incandescent light efficiency 15lm / W, then 140 ÷ 18 = 9.33W
Light effect is not very high, about 70lm / W or so look
2WLED lamp because the power efficiency is relatively low
So 2W LED lights are at least equal to 10W incandescent
