What has your experience been? What brand of bulb are you using?
Happy to answer your questions.
Most of my LEDs were purchased at Costco for dirt cheap prices. Like $1 USD for a 4 pack. They occasionally have special deals where the utility company subsidizes the price so they are ungodly cheap. I've mostly stopped looking for bulbs because I have a houseful now. Costco also reduces your risk with their easy returns.
The brand is Feit electric which seems to be a common bulb brand around here. Nothing special as far as I can tell.
And I cannot recall an LED bulb failing. My CFs were also not generally failing. You might call an electrician to see what they might suggest. I suppose there are power supply situations that are unfriendly to LEDs.
The last LEDs I bought are Feit electric Item 1715918. These are 100 watt replacement LEDs with a switch on them to choose the color (temperature) of light between soft white (2700K), bright white (3000K), cool white (4000K), daylight (5000K) and cool daylight (6500K). Seems like a great idea to let you choose your color. I prefer daylight over the harsher whites.
cobra89 mentions Philips brand and I have heard they sell some of the best bulbs. I don't think I have any but I may eventually get some for specific applications.
