Q:How much LED 150W downlight spiral energy-saving lamp replacement
I do the lighting! First, where do you use 150W energy saving lights? With 150W energy saving lamps will only be used in industrial and mining lights, indoor general lighting is unreasonable. Simple answer to you, the general energy-saving lamp (60ml/W) lumen is led (120ml/W) half, that is, 150W energy saving, with 75W LED can replace brightness!
Q:LED lamp is mainly used in where
LED downlight with much more local hotel, shop, office, family etc..

Q:What is the role of LED downlight
In fact, choose a good day Lantern is a LED lamp energy saving function, ordinary energy-saving lamps should be minimum 5W is generally 11W, a LED lamp bead is 1W, long service life, ordinary energy-saving lamps have radiation, light at 400 nm will produce ultraviolet light is harmful to people, UV will attract insects so the general energy-saving lamp has bugs in the circles above, the LED will not produce ultraviolet
