Question: Drawbacks? This is only $13 but newer felt is $25?
Document: The LED light is excellent: it comes on instantly at full brightness. Uses very little energy as can be felt by touching the bulb - it's only slightly warm.
I very much doubt it would start fires, I've felt an incandescent get hotter than this does, but I'd rather not have this bulb enclosed to thoroughly.I just received the Phillips 11 Watt Soft White bulb and must admit that it seems like a better bulb. It stays cooler and has a slightly warmer light temperature.
I bought three bulbs at the same time based on reviews by that product rating magazine (that you aren't supposed to mention by name...). The FEIT 60 Watt equivalent was my favorite. It's a good light that approximates something close to an incandescent bulb. It was a little whiter and almost felt like daylight. I think it was cheaper than the Samsung 60 Watt equivalent too.
Then, before I threw out the incandescents, I looked and found that they were 100 watt bulbs. I'm using just 13.5% the energy and getting better illumination.
Very nice looking light bulb, bright and cool. 13.5 watts power usage as to a 75 watt incandescent equivalent. I really like it.
I bought 4, 1 went bad after 3 months - can't return it - very unhappy. They are very expensive - then I have to throw it away after such a short time - $13.11 plus shipping. Not worth it! Now shipper will give only a partial refund, and I have to pay for shipping!
PROS:-Relatively inexpensive, though there are several other A19 style bulbs at or around this same price-Cool looking heatsink-That's it.CONS:Where do I begin? ?-13.5W consumption for a 60W replacement, whereas competitors bulbs only take 9W for the same brightness (850 lumens).
If the heat is the same, I don't see why I would pay $14.99 for each bulb when CFL's are so much cheaper now. Obviously they aren't going to last 22,8 years either. I am returning the defective bulb. Will probably take a store credit and get the CFL 13 watt bulbs.
I ordered and am using three of these bulbs, the LED 13.5 Watt LED Omni - 60W Incandescent Dimmable Replacement Bulb from Feit Electric Performance is very bright and appealing in the fixtures I use them in (a ceiling fan with Glass Globes that point downward at an angle). This and the Phillips A19 are my favorite new LED bulbs for sale through Amazon.
Bought the Feit and Philips LED bulbs to compare side by side.Philips was a lot better. Brighter, dimming works and looks better as well.It is possible to dim the Feit bulbs but only partially and it is not a very comfortable light.Spend the extra money and buy the Philips bulbs, worth it.Philips 423798 13-Watt (65 Watt) BR30 Indoor Flood LED Light Bulb, Dimmable
