Hello, Can anyone weigh in on whether or not the flourescent bulb for this "Alvin" Swing-arm Task Light hums or buzzes like many flourescent bulbs?

I have very sensitive hearing and I have never heard a hum or a buzz until the head started shorting out after about 15 years of use. I am going to buy the same lamp as soon as I can figure out if the lamp separates from the clamp so that I can put it on a table base.

I do not have any idea...but I have experienced the same phenomenon with two 23W LED bulbs. It has happened twice and is intermittent. Both times, adjusting the brightness slightly either up or down stopped the flicker and buzzing. This has never happened on switches that control one bulb one bulb.

I used Leviton 6674-P0W SureSlide Universal 150-Watt LED and CFL/600-Watt Incandescent Dimmer $18. also available at home depot. No issues and no buzzing. Easy to install.

It shouldn't be too difficult because it's a fairly common size for a blacklight bulb. One thing I'll say (if you haven't yet decided to buy this blacklight) is it is EXTREMELY quiet! I've had other blacklights that emit constant hums - but this one is dead silent.

Cree customer support said "some humming is normal with our bulbs". She suggested ELV (electronic low voltage) dimmers, which run about SEVENTY bucks. I can verify by personal experience that if there are many bulbs or they are close to your ears, there can be an unacceptable buzzing with the $20-$25 "C-L" dimmers you can get at Home Depot. The Cree list of compatible dimmers is at http://creebulb.com/Content/downloads/product_info/cree_dimmer_compatibility.pdf Check for the ones that say ELV.

Never had a problem!! My lamp (knock wood) has worked perfectly since I installed it. My old bulb was not completely burned out so I saved it in the box for next time. If you have the old bulb re-install it and see if it too flickers. If it does there is a problem with the set. If it doesn't there is a problem with the new bulb. Best advice I can give.

I do operate (4) of these lights in my ceiling fan and have no issues. The room is a lot brighter than the Compact Flourescent bulbs they replaced. I have ordered over (30) bulbs, some do give a little buzz most don't. Im still pleased with the purchases.Randy

Mine does not buzz. However, if you are looking for a serious strobe, keep looking. This is more like a weak blinking light. No strobe effect at all.

I have had my lamp for one month now, and I have not heard any buzzing noises. Hope this helped, you might want to get a return.

Don't know about buzzing. Mine never lasted long enough to buzz. Don't buy these bulbs. Gone in a few weeks.

I don't have them in lamps that are very tight around the fan, but I have noticed an intermittent fan noise in one of the 150W bulbs I purchased that goes in a lamp that has a glass hemisphere that acts like a megaphone. I'm not sure if it's at a resonant frequency, or just a random issue in one of them. The base can get very warm (I just put my hand on one that's been going for an hour and a half overhead), but not too hot to touch. I'm not sure how hot is too hot, though PacLights may have more information.

I can't hear any buzzing from my CFLs. But that might be just my hearing. I see that another answer talked about the lights failing quickly. While I have not had that problem another customer did. The bulbs come with a support phone number and are distributed by Home Depot.

Not for me, if you are asking about the Phillips LED light bulb with the yellow "glass." I have six of them, none buzzes or vibrates when dimmed to any level of illumination. However, minimum illumination (maximum dimness) is not as dim as that given by a tungsten or halogen bulb.

I have a 55" led and had this buzzing that would only happen at night. A flood light was on the same circuit in my house and when it would turn on I would get the buzz. When I turned it off the buzz is completely gone.

I also use a dimmer and no buzzing sound for me .Make sure the hot and neutral aren't switched (black is hot white is neutral)and the fixcture is properly grounded(green).

Funny you should ask about CREE bulbs & this dimmer... I switched to the CREE bulbs and bought this dimmer as it's listed as compatible. HORRIBLE buzzing, I took the bulbs back to the big box retailer immediately. After much trouble shooting, including testing other bulbs... I realized the low load was the problem. 75w equivilant (13.5w) CREE LED bulbs got rid of the buzzing. FYI: my fixture requires 5 bulbs. I need a minimum of 60 watts total to keep the buzzing at bay in that fixture. I had the same issue in a 3 bulb fixture that needs a minimum of 40 watts.
