B. Wattage and color temperature
Normal 7-9W is enough, color temperature 4000k or 3500K, the same space color temperature should be unifiedlike my home to pursue warm lighting effects
So the main light, spotlights all choose 3500kbelongs to the warm yellow light; Kitchen can consider 4000k neutral light.
General 5w downlight can shine 3 square meters, 7w can shine 5 square meters.
C. Anti-glare
Anti-glare is very important for the selection of lamps, anti-glare lamps and lanterns for the eyes will be more comfortable.
Deep anti-glare > no deep anti-glare, with deep anti-glare see light not see the light, in the light of the eyes will not produce visual fatigue due to glare otherwise the light pollution is too serious, a look up will be dizzy. Choose shade angle > 30 ° spotlights can be.

Why choose LED downlights?
Compared with traditional downlight benchmarks, LED downlights have irreplaceable advantages
More energy-saving: The current luminous efficiency of LED downlights can reach 90lm/W
which can save more than 50% of energy than traditional halogen downlightsand CFL GU10 downlights.
More environmentally friendly: LED downlights do not contain harmful substances such as mercury, and no pollution to the environment.
The protection of the global environment is more beneficial.
Lifespan: The lifespan of LED lamps is 50,000 hours. According to six hours of daily use, one LED lamp can be used for 20 years
