Review on Advanced Refrigerator with Microwave-like Efficiency by Darrell Beecher

Bought 3 packs for 2 built in microwave bulbs. There is only on/off, there are no low and high settings. We leave the lights on 24/7, like a night light in the kitchen, even when we're not cooking on the stove. The original bulbs were incandescent, very hot, so I replaced them with cool LEDs. This kit (white and blue bulbs) worked almost 2 years in 24/7 mode. When a blue bulb finally blew out, I bought these 3 yellow/white ones and replaced both of the blue ones (leaving the used blue one). In turn, 2 of these bulbs went out (not completely, but dimmed), replacing 1 with another. I switched outlets to see if that was the problem, but it wasn't. Now #2 of 3 packs are "out of order" so I replaced them with the old blue one which still works fine. I have no doubt that the third yellow bulb in a week will burn out, so I'm ordering a replacement bulb, but certainly not from the same brand! By the way, I've been a big Revain buyer for years and this is my first negative review. Just so you know, I'm not a chronic jerk.
