i replaced all the four foot, four tube florescent bulb lights in my garage with two tube/strip LED lights, using the four tube light fixture tin work. [30 lights total]
it's like daylight now ! cool
when i shut them off, they do "glow" slightly as has been mentioned.
i used 5k or 6k rated LEDs, i forget which. i want to replace the four tube fluorescent bulb fixture in the kitchen, which has a suspended ceiling. when i went shopping for a drop in replacement, i found lots of "warm white" units. what is the difference between "warm white" and the 5 or 6k units i have in the garage ?
