Cannot rate these lamps any lower. I bought five packs even though I only needed two. They had to replace the lower wattage lamps. I've waited a long time for the lights to be installed. NONE worked. Lower wattage lamps were returned to lighting fixtures. Please check these lamps as soon as they arrive. I've waited too long to try to return the lamps. All I had to do was eat the purchase price of non-working lightbulbs.
