Review on Industrial Electrical Lighting Components - Philips LED 3 Way Frosted Light by Kyle Gilbert

Update 7/10/21: After more than 2 years of use, all 4 bulbs are still working fine. Two reading lamps are used 6-12 hours a day. I bought a 4 pack and all the lamps have been in use for 8 months, they are excellent. Little heat than incandescent bulbs, cooler for summer reading and it makes a difference. Come to full brightness almost immediately. No hum, no hiss from those four LEDs. They're pricey at $12 each, but I'm sick of old 3-strip bulbs burning out. I will buy again.
