Ping Don Klipstein $ store CFLs
I know you (Don) have often called the CFLs one buys in dollar stores
"stool specimens". I just wanted to alert you to the fact that not *all* dollar store CFLs are necessarily such. (I've certainly bought my share of ****ty bulbs there.) Just picked up a 2-pack of "60-watt" bulbs, pretty nice-looking ones (with a standard bulb-like envelope instead of the usual "twirly" tubes) for a buck. Made in China, natch, but apparently designed and marketed by an American company (Sunrise Lighting in Gilbert, AZ). They take a while to warm up but then give a very pleasant light, certainly not the ghastly bluish glow I've seen from other dollar-store bulbs. (Package, of course, says nothing about color temperature.) One odd thing I noticed that may not be limited to these bulbs: the comparison to incandescents on the package seems a little screwy. Here's what it says: STANDARD INCANDESCENT: 60 watts/540 lumens CONSERV-ENERGY COMPACT FLUORESCENT: 14 watts/855 lumens Now, leaving aside the accuracy of the lighting measurements (lumens), isn't this an apples-oranges comparison? I thought the idea was to compare a CFL to the equivalent incandescent bulb in terms of light output. (Of course, this comparison makes the CFL look better--meaning even more efficient--than the incandescent bulb.) Anyhow, they seem like well-made bulbs. Time will tell if they have a decent lifespan. -- You were wrong, and I'm man enough to admit it. - a Usenet "apology" |

One odd thing I noticed that may not be limited to these bulbs: the comparison to incandescents on the package seems a little screwy. Here's what it says: STANDARD INCANDESCENT: 60 watts/540 lumens A standard 60 watt 120V incandescent produces 870 lumens. 540 would be not far off for 3500 hour vibration resistant version (585 lumens), 230V version at full voltage (less due to economies of scale having to do with filament thickness - 545 lumens at 230V), or 120V-lumens of 130V versions that arelonglife even at 130V. CONSERV-ENERGY COMPACT FLUORESCENT: 14 watts/855 lumens Now, leaving aside the accuracy of the lighting measurements (lumens), isn't this an apples-oranges comparison? I thought the idea was to compare a CFL to the equivalent incandescent bulb in terms of light output. (Of course, this comparison makes the CFL look better--meaning even more efficient--than the incandescent bulb.) A 14 watt CFL is supposed to produce about 800-900 lumens. Anyhow, they seem like well-made bulbs. Time will tell if they have a decent lifespan. Do they mention UL listing and FCC ID? Meanwhile, the most similar dollar store CFLs I have seen so far yet are the "Capitol Electric" ones, which I have seen at only one dollar store, and not in the pastt couple years to so. They had good color. They claimed to consume 11 watts and produce 550 lumens of light, but light output looked to me to be about 400 lumens. - Don Klipstein ) |

If so, what was the name of the store? Meanwhile, they are supposed to have FCC ID on them if they are sold in USA and have electronic ballasts. - Don Klipstein ) |

Also, the name "Sunrise Lighting" is new to me - not any of the 19 or whatever I have seen so far of dollar store stool specimen CFLs. Were they actually purchased at a dollar store? If so, what was the name of the store? It's a bona fide dollar store (everything there is $1, 99% from China) in Berkeley on University Ave. Don't know the name; will check it next time I go by there. It's small, but one of the better stores of its type: the owner is pretty savvy and knows what to buy. Maybe I'll ask him about the bulbs next time I go there. Meanwhile, they are supposed to have FCC ID on them if they are sold in USA and have electronic ballasts. Hmm; don't know what to say 'bout that. Here's their website: http://sunriselighting.com Takes a ****ing eternity to load due to extreme bloat. I can't even tell you what's there 'cause I'm still looking at the initial screen. -- You were wrong, and I'm man enough to admit it. - a Usenet "apology" |

I'm sorry I included this link. Their website was apparently designed by a TOTAL ****ING IDIOT. After waiting 5 full minutes for *something* to load (no indication of what was loading, no "skip Flash intro" link or anything), I get a page with a picture and a very strange menu in the middle of the picture with a band of links across the middle. Click on "Deco Series Lamps" and I get a page that consists of a TOTALLY UNREADABLE image that's apparently a reduction of a 2-page spread. Click on THAT link and now I get a HUGE image (3341 x 2250 pixels) that has information about a bunch of bulbs, including the ones I have (item # SGF-14). No more information that what's on the package. The date on the front page is 2006-20007. We're ****ing doomed. -- You were wrong, and I'm man enough to admit it. - a Usenet "apology" |

I thank you for exploring this, and I hope the relevant CFLs are not doomed to being "insufficient-while-significant improvement" (My Words) above the "stool specimen ones" (My Words). I could use a reminder as to what these are, how they would appear to me, and where I can buy them, so that I can say "Outright in my experience" or "the like" should I find them to be "subpar". - Don Klipstein ) |

I could use a reminder as to what these are, how they would appear to me, and where I can buy them, so that I can say "Outright in my experience" or "the like" should I find them to be "subpar". So, further research results: my crack team here at Nebenzahl Laboratories, GmbH, have concluded that for most applications, these cheap CFLs have an excessively long warm-up time. About 5 minutes to reach full brightness. OK for a light you're going to leave on for a long time and don't mind waiting to warm up. Interesting: the day after I posted that original message I installed a light fixture for a customer who gave me an identical-looking 60-watt CFL to put in it. When I turned it on, it seemed to come up to nearly full brightness immediately, so apparently it's a much higher-grade lamp. (They got it at Home Despot. Sorry, didn't get the brand name on it.) So there seems to be quite a range of bulbs that have the identical appearance. (I'm assuming my customer paid more than $1 for the 2-pack.) -- You were wrong, and I'm man enough to admit it. - a Usenet "apology" |
