If you’re lucky, you’ll be hung up on immediately upon the phone ringing to the next available representative. If not, they’ll place you on an indefinite hold. I’ve waited as long as 35 minutes before having to get on with my life. Lastly, you may actually get through to a person (I did on my 2nd day trying). Joanna helped me and seemed to be quite tired. The job probably is boring so that didn’t bother me. What did was how quickly she got annoyed when I didn’t have the bulb in my hand ready to read off the model and serial number/manufacture dates or whatever they were. There are no prompts telling you to have this information ready. I did have my invoice ready to give the purchase date, but that’s not enough. You’ll also be answering a series of questions to find out where and how you used it along with any programmable or dimmer switches. If you don’t pass the questions, expect to be denied a replacement bulb.
Feit’s business hours are 9 to 5 Monday through Friday so if you work, it’s going to be hard contacting them if needed. Calling towards the end of the day ensures you’ll just be put on hold and disconnected as workers likely want to be punching out at 5 and walking to their cars at 5:01pm. You can try emailing them, but I still haven’t heard back from them after a weeks’ time. In the end, I was told I should have a new bulb in the next 2-3 weeks. No tracking number or no email confirmation, I was just told to wait. If you choose to buy this bulb, don’t expect any sort of hassle free exchange.
Wow! Yes, it's big...clowny big. It's also incredibly bright. I'm using 2 (out of 4 sockets) of them in my 20' x 20' garage with a 9-foot ceiling and it very well may be enough that I don't buy two more for the other two sockets.
- Seems solid and hefty.
- Fits a standard medium base socket
- Color is accurate. See attached pic for my eyeball estimate of the temp. It's advertised as 6500K but I'd say it's a bit more toward the 6000K range.
- Well ventilated on the sides and the bottom (for upside down use).
- Can be used in damp locations.
- Instant on and starts at full brightness to my eye.
- None yet.
I'll report back regularly as it ages.
2-Year Review--Both bulbs are still going strong in a garage environment in Wyoming (hot summers and cold winters). I did eventually add 2 additional bulbs (the soft white version) in order to get as much light as possible in a work environment. The warmer color of the soft white bulbs, when mixed with the two daylight bulbs, also helps give me broader spectrum coverage and a little better color rendition throughout the garage.
Talking about the item itself:
- you WILL experience some delay when you turn it on but it's hardly noticeable, like maybe 1/10 of a second
- once it's on, unlike the 'cheaper' fluorescents that need to warm up, it shines at or close to full brightness immediately
- it's a bulky, significantly wider and longer than the 150W incandescent equivalents and it may not fit all fixtures where a regular 150W bulb used to fit
- does not work well with a dimmer - it's either on or off [I tried it with one and it did come on at full brightness but something is telling me that you may shorten its life when used this way]
- the light is bright, so bright, I would not stare at it directly - I did once and I saw 'ghosts' for the next 15-30 minutes
- the color of light is closer to 'solar' than what our 'incandescents' deliver, less yellow, more blue
- unlike neon lights, there's no flicker
- it consumes less power when compared to an incandescent
The above were my subjective comments. Here are the specs, as the manufacturer lists them:
- Light output: 2800 lumens
- Energy used: 42W
- Life: 8000 hrs.
- Color temperature: 6500K
- Electric charge: 610mA
The major issue I have with the fluorescents is their lifespan. Maybe I am unlucky but, after replacing nearly all my light bulbs in the house - a few dozen - they seem to burn out more often. My first couple 40W I bought a few years ago (a different brand), in fact, died after about one year, I hope this is not the case again because we are paying top dollar for these environmentally nice devices.
So far, I see no reason not to award this bulb 5 stars but, if it dies on me before 2-3 years, I promise to come back and update my review. For the record, the maker promises a 7-year lifespan and $152 (???) savings per bulb.
December 2013 update:
On their 55th month, they (I bought a 2-pack) are as bright and shiny as on 'day one' and they've been on for many hours because I telecommute most of the time and my office is in the basement. I haven't done the math but I'm quite confident that they've paid for themselves already, probably several times over.
I bought 2 more in December, 2009 and no burnouts yet.
