Duracell Procell A19

I ran across these while at the local Batteries + looking for a battery. Duke/Progress Energy has a rebate going for a lot of LED bulbs there. It isn't available at Lowe's for some reason. The weird thing is that they offer them on 4000k and below bulbs but not the 5000k bulbs. These bulbs are available in 40, 60, 75 and 100w with color temps of 3000k, 4000k and 5000k. I picked up one each of the 60w versions.

The 3000k and 4000k versions were 7.99 each and the 5000k one was 17.99. All of the 60w versions are listed as using 11.5w. Light output is listed at 800 lumens for the 3000/4000k versions and 820 lumens for the 5000k version. The box says they are dimmable, suitable for dry/damp locations and do not use in fully enclosed fixtures. I'll list the bulb used in each picture and the power being used according to my watt meter. The watt meter shows 1 even when nothing is plugged into it so take that into consideration. Bulbs will be listed left to right, top to bottom in pictures with multiple bulbs. All of them are 60w equivalents. They have a 5 year warranty.

Duracell 3000k - kept bouncing between 13 and 14w



Duracell 4000k - kept bouncing between 13 and 14w



Duracell 5000k - kept bouncing between 13 and 14w



Sylvania - 13w



Switch clear - 15w



Switch frosted - 17w



Cree - 11w



Duracell 3000k, 4000k, 5000k



Switch clear, frosted



Cree, Sylvania



Cree 5000k, Duracell 5000k - It looks like they are pretty close, if not exact, color wise.

I threw a few of the 4000k ones in the ceiling fan that's in my "office." I just need to find a dimmer switch now. I haven't had much luck trying to find a list of compatible ones yet. So far I'm satisfied with them. They do seem to put out more than 800 lumens. I might try some dimmers to see if I can find one that works. I'll be sure to report here if I do.

They also had Duracell snowcone style A19s and some PAR bulbs at the store. The snowcone style ones only come in 3000k and are not dimmable. They do have a lower energy consumption according to the box though. I didn't look that closely at the PAR lamps.

Great photos - very nice. Have you noticed any 120Hz flicker (as has been mentioned with the Cree's)?

That 4000K looks perfect for general lighting.

Exactly what I've been waiting for! I don't understand the appeal of "blue" 5000K+ bulbs in the home, and 2700k is just a bit too warm for me.

I finally found a dimmer compatibility list of the Batteries+ website. It looks like the Duracell LED bulbs are exclusive to them. http://www.batteriesplus.com/t-led-compatible-dimmers.aspx

I picked up a TGCL-153PH. There was all kinds of flickering at lower settings when I first installed it. I tried adjusting the dimming range and it didn't make a difference. The flickering has now gone away though.* :shrug: I settled with a point slightly higher than half way. They get pretty dim at the lowest setting. I don't hear any buzzing from one of the bulbs. The others buzz at varying levels. There is a 1/2 to 1 second delay when turning them on throughout the whole dimming range.

* There is one thing weird about using these on a dimmer. At least for the one I'm using. It doesn't matter when the adjustment dial is set. Sometimes they don't turn on and stay on. They'll flash at a rate of about 1 second off, 1/2 second on. Those numbers are guesses and not actual times. It is completely random. My only thought is that is has something to do with where the AC waveform "wave" is when you turn the switch on. Maybe somebody else can shed some light on this problem.

I noticed on the dimmer list it shows tgcl-153p and tgcl-153ph. Does anybody know what the difference is?

I don't have a way to check for flicker other than my eyes. I don't notice any visible flicker. Then again, I don't notice it with CFLs unless they or the ballast is about to die. There was some flicker at first while using the dimmer. See what I typed above the quite.

I'm about to find something else to do with the 4000k bulbs I have in one room. I have them on a dimmer because there are times I just want a little ambient light. The problem is that sometimes flash about once a second sometimes. I have to keep turning them on/off until they stay on. They do dim just fine without any noticeable flicker though. I'd say they go down to about 5% of full brightness. I wish the Crees and Switch bulbs dimmed down that much. There isn't much noise either with the bulbs I have installed. I have a couple extra that makes all kinds of noise on a dimmer.
