I love this bulb! The light from this LED is exactly as advertised--very bright, omnidirectional, and in the same pleasing color of incandescent bulbs. Even my very picky sister, who claims CFLs give her headaches, is satisfied with the L-Prize light. There is absolutely no flicker or hum to bother her, and the color faithfulness is fantastic. Its 92 CRI (Color Rendering Index) is much higher than any competing LED or CFL in the A19 warm white form factor, and very close to the maximum 100 on the CRI scale. Cheap, imported LEDs can have really horrible color, like early CFLs had. If you go with any other bulb, always look for an Energy Star seal of approval, which guarantees at least an 80 CRI (the L-Prize bulb will get Energy Star status very shortly). Color temperature is different from CRI, but just know that it produces warm, yellowish light exactly like an incandescent bulb, not harsh blues or ghastly greens like first generation LEDs and CFLs. And this bulb is very bright--at 940 lumens, it's 17% brighter than the 800 lumen output of a 60W incandescent.
There is a very slight (but noticeable) delay when turning it on--perhaps 1/5 of a second. It does come on at 100% percent brightness though, with no 'warm-up time' like CFLs need. This bulb can be dimmed smoothly down to 10% of output, but the light quality suffers. Instead of transitioning to a romantic and orangey candlelight glow, these get a progressively harsher, unflattering color. I recommend just using them close to full brightness. Also, like most LEDs, these should not be used in totally enclosed fixtures or you risk shortening their life. Finally, some may find the appearance of the unlit bulb ugly if placed in unshaded fixtures.Read more ›
Philips customer support is awful, by the way. The most recent attempt I made to get help with this bulb's dimmer compatibility problems resulted in my being transferred to "product management": I was left on hold for 10 minutes until I finally hung up.
This bulb is bright and gives off a warm, "soft white" light similar to an incandescent bulb, whose size it resembles. It only consumes 10 watts instead of 60, and it is supposed to last for many years of use.
The Philips LPRIZE LED bulb is heavy compared to an incandescent bulb or even a CFL bulb. It emits light in three distinct partitions, so it is best not used where the bulb will show. This LED is still incredibly expensive, even when discounted by some electric utilities. Most of all, if your application involves a dimmer you should probably look elsewhere until Philips identifies which dimmers actually are compatible--if any.Read more ›
I was happy when Philips came out with their 12.5 watt LED bulb--the one that looks like this one, except with a dark gray ribbed base and an orange (rather than yellow) top. While the light from that bulb is not as beautiful as incandescence, it's also not unspeakably hideous. It has a very slight fake pink tinge that I can live with, though it's not ideal. I replaced several of my incandescents with it.
When this bulb came out, I read that it had a higher CRI (Color Rendering Index) than the 12.5 watt version, 93 instead of 80 (out of 100). Supposedly, the higher the CRI, the less the light makes the objects it falls on look weird and fake. Because I liked the 12.5 watt version, I was eager to see if I would like this one even better. I decided it was worth $50 to find out.
Turns out I love this new bulb. No fake pink tinge, no uglifying. It's completely acceptable. The light it sheds looks almost exactly like the light of an incandescent bulb. It's slightly brighter than the (already very bright) 12.5 watt version, it turns on immediately, it sheds light in all directions, and it doesn't heat up my lamp.
The only thing I don't like about it is the price. Once it comes down, I'm replacing my incandescents with this bulb.
