Sylvania #14700 50-watt PAR20 wide flood halogen bulb

I use two of these in a Broan Allure hood, which has two bulbs and two brightness levels. We never turn the lights off. They are usually on the low setting, and occasionally switched to high. They are rated at 2500 hours - presumably on full power. That's about 3.5 months, but I expected to get longer use because they are almost always dimmed.I started using these bulbs on May 25 of last year, and today is March 17 and the first one has gone out (the other is still going strong). That's nearly 10 months; exactly 296 days, or 7,104 hours of continual use on the dim and occasional bright setting.The light is warmer than I expected, which is nice. At night, when all the lights are out except these, the kitchen has a nice warm feel. The light spreads out very evenly and the light of the two bulbs blend into each other nicely - you don't really notice that the light is coming from two bulbs which are 20 inches apart. Our previous hood had a single light, and we were concerned that the two-lamp hood would produce two distinct hot spots, but this is not the case.One reviewer said the bulbs are 2.75 inches in diameter. Mine are exactly 2.5 inches and fit my Broan Allure hood with room to spare.UPDATE: Today is Nov 25, 2014. I have not replaced either the original long-lasting bulb, or the replacement for the one original bulb that failed. The lights in our dual-light Broan hood are still always on reduced setting, every hour of every day.

I installed two of these in my Broan range hood, and they really light up the stove top. My hood has 3 brightness settings and these bulbs do work with a dimmer. LED bulbs were my first choice, but I think LEDs are still too expensive for this application (Dec 2010) where usage is for short periods of time. I bought these halogen bulbs through Amazon from CFA Trading, and they shipped very quickly.Beam Spread = 40 degreesLight Output = 550 lumensEnergy Used = 50 wattsLife = 2500 hoursVolts = 120

These bulbs are erratic in their quality. One was perfect and easily screwed into my range hood and is working just fine. The other one, however, had irregular and pieces of material at the top of the part that connects with the screw in part. This causes the bulb not to fit snugly into the socket and sometimes it will just go out - no light. The Seller e-mailed me to inquire about my satisfaction with these bulbs and gave me a full refund for the one that works erratically, which I very much appreciated. So their customer service is excellent. And this problem is not the fault of the Seller - it's Sylvania's defect. I'm trying to find out if it would render the bulb completely useless if I file down some of these rough, irregular areas. I am very pleased with the one that works correctly. Sylvania is not up to par on it's quality control and this bulb should not have passed their inspection. If you get good ones, I would highly recommend these bulbs.

While I like the look of the light itself, I'm a little upset over the longevity of this bulb. I use these bulbs in my bathroom, and they only seem to last barely 1 year before dying. If the 2500 hour listed bulb life was correct, that would mean I'd have left the light on in my bathroom for nearly 7 hours every day, which isn't even close. I'd estimate that I got a 1000 hours of life out of the bulb. By contrast, the twisted-style halogen bulb that I use in my floor lamp in my living room has lasted me nearly 2 years already.

Thanks to other reviewer Seth for mentioning that this bulb fit into his Broan range hood.Exactly the hood I have, and they do fit.My original halogens were 2" wide at the lens. These are 2 3/4" wide, but they did go in (a little snug).Amazon and Sylvania need to do a much better job of telling us shoppers specs like that on their products. Too much guesswork otherwise.Hope this helps.

the first two bulbs didn't work, returned for replacement. the replacemet bulbs worked but the one had a smaller base on it so the only way to get it to come on was for me to hold it up in the socket. I am now waiting for a bulb to replace that one and I do hope that the base is the right size . the one that needed to be replaced wouldn't fall out of the socket , it would not stay up in the socket enough to make contact.

This is a commodity item that fits my expectations. It is the proper size, provides light with the proper warmth (color temperature is warm white about 2800K I would say), and has the proper amount of lumens (it matches my other 50 watt bulbs from another manufacturer.I purchased this to replace one of the four light bulbs in my Viking Range Hood. Viking, unsurprisingly, offers to sell you the same bulb for 4x the price. This one was an exact replacement for the burnt out bulb at a fraction of the cost.

We have track lights in our office that use this bulb. The short neck is near impossible to find in stores unless you go to a lighting specialty store, where the price was a sticker shock for me, so I checked out Amazon. I reorder these whenever we need more bulbs. No more running around looking in stores. My only complaint is that they are very difficult to get in and out of the track cans as the face of the bulb is so smooth. Otherwise I would give it a 5 star rating.
