...................."and another thing"...............(Clouseau)
Comparing the yellow light of an incandescent bulb to pure white 5,000K LED light is deceptive. An incandescent bulb casts light every which direction. It is difficult to get a tubular shaped LED lamp to cast even lighting throughout a cube shaped space. I am vulnerable to lower number heat color. I can read (for example) with 10-watts of 5,000K light and have difficulty reading with 20-watts of 3,000 K lighting.
I drive ten watt LEDs at their full 1000 ma rating (10-volts). The light is an inverse cone and the full ten watts is concentrated inside the cone.
