Rated 4 out of 5 by 2 reviewers.
Rated 4 out of 5 by Decent, bright light, but high failure rate / low life span I've purchased now 12 of these bulbs (6 of the 4100K/23W and 6 of the 4100K/19W variety, otherwise the same bulb) over the past several years. I went with them because of their reasonable price, bright light, and stated life span. On the whole, they produce a good, solid white (but not blue) light. However, they start at about 10% brightness and take a full five minutes to really warm up, making the occasional quick nighttime kitchen trips a rather dim experience. I'm noticing that these bulbs burn out often, almost as often as the halogen bulbs they replaced. This is on a non-dimmed, standard switched circuit (kitchen canister lights). This life span issue occurs both with the TCP 19W and 23W models. On average, I get about 1.5 years' life out of these bulbs with average daily usage of about 3-4 hours. This is in contrast to the 7 year stated estimated life span. Out of the first 4 of the 23W model four I've purchased, I've had to replace two in the past 1.5 years. That makes these bulbs as expensive (energy use included) as a decent 80W Halogen R38/R40 bulb. I've noted the "burned out" ones seem to suffer from the internal tubing coming unglued from the base and getting "wiggly" inside of the glass housing. This may be a manufacturing process issue. In all, these ARE good bulbs, and I DO like them. But I would caution against buying them to replace higher-wattage incandescents simply because of purported cost savings. What you save in energy use, you'll spend in buying replacements. If you're looking for a bright, white light, this bulb is great, just keep the life span in mind. November 29, 2013
Rated 4 out of 5 by Good for can lights I have about a dozen of these in basic can lights in a finished basement. They are more expensive than the discount bulbs you can get at the big box stores but better quality and the specific color temperature I wanted (4300K). They give out even light, and warm up to full brightness fairly quickly. They don't buzz and they only flicker when they start to die. Average life is somewhere between a year and two years with all-day usage. June 10, 2011
