About 4 years ago I replaced all the CFLs in my house with these. The rep gave a presentation at a local restaurant.
My wife was eager for the change, thinking the CFLs might be exacerbating her seizures. Rep said they should last 25 years, and that if any bulbs failed we should return them to you for replacement so that they could evaluate the cause of failure. The packaging says they should last up to 22.8 years. After about 3 years, LED elements started going dark.
Turns out there's a 3 year warranty.
Viribright reluctantly replaced the 8 bulbs that had failed (out 30) with an improved model, but I had to pay to ship the bad bulbs back to them. Since then, they've continued breaking down, and I have no recourse except to replace them.
