compact fluorescent bulbs...extremely slow
I bought some compact fluorescent flood bulbs to replace the recessed
bulbs in my kitchen as they burn out. So far I've got 2 installed. Both of them have this problem. About half the time they work fine. They have the normal delay that compact fluorescent's have, but that's fine. The other half of the time, only the very upper part of the bulb lights. Then the light slowly "creeps" down the spiral. Takes about 5 minutes! Anyone else experienced this? |

I installed them and immediately thought that I was going to bring 'em back (they were $5 each). They are very dim when starting up, but after a couple of minutes are brighter than the originals. I haven't noticed if the light "creeps" or not, but I suspect it does. For me, the energy savings outweighs the delay. |

Are your Recessed lights on a dimmer? Nope...not this set. I was planning to eventually replace all the kitchen bulbs with these, but there's no way I could have 7 of these things taking several minutes to light up! |

Then the light slowly "creeps" down the spiral. Takes about 5 minutes! Anyone else experienced this? I have had similar effects, from the bulb being cold. This varies with the temperature of the bulb. However, in my experience spirals usually warm up in half a minute to a minute. Now, another issue for compact fluorescents in recessed ceiling fixtures: They may overheat and short life may result. It is recommended to use ones that are specifically rated to take the heat of recessed ceiling fixtures. The Philips SLS ones of 15, 20 and 23 watts (though not the dimmable one) are rated for such use. Otherwise, keep your fingers crossed - they may or may not burn out early. - Don Klipstein ) |

By the way...the brand is Lights of America (I had a coupon). :)
I wonder of GE would be any different? I have CF's in two floor lamps and two closets, and I've never seen the problem. |

The problem is in not knowing what "down" means.
Upside down = base up. Anyhoo, CFLs vary widely by brand and even by model for warm-up time. I have some LOAs and Feit Electrics that come on full intensity, and some of the same brand (earlier production?) that take a bit to brighten up. I have some vanity-globe style Sylvanias in the bathroom that are nightlight-bright for about 10 seconds and take another 30 seconds to come up full brightness -- very annoying, especially since the globe-style are so much more expensive than a plain spiral. I also have a GE that has a totally dark delay, then comes on, which annoys me more than the Sylvanias. My advice is, try different brands until you find one that you like. Kind of expensive way to go about it, though. I wish these things were rated on the package with the time it takes to go, from off at 72*F, to 80% of full rated brightness. |

Ovens require oven bulbs or appliance bulbs rated for such heat. Also, I recommend against CFLs for motion sensor lights, lights in bathrooms used mainly for short trips, and most usage of closet lights due to low ontime per month and low onmtime per start. - Don Klipstein ) |

If your buying these from a grocery store or similiar.....this is a no no. You get what you pay for. Your better off going to a specialty lighting store which will have quality bulbs, etc. Please Note that even the HD or Lowes does not have top quality lamps .......or not as quality as a specialty lighting store. You might try this.....buy one.......and see the difference. Dean |

I have some vanity-globe style Sylvanias in the bathroom
Where do you even find those? It was either Lowes or Home Depot... probably Lowes. They were not prominently displayed and were often out of stock, took me several trips to find them and collect 4 of them. Well, that lets out most ceiling fixtures. Guess you can use 'em only in lamps. I guess I'm lucky, most of my ceiling fixtures have the bulb horizontal. I do use CFLs in my ceiling fan, where they hang at about a 30 degree angle from vertical. I had one set of straight CFLs that only lasted a little over a year, but I now have a set of spirals in there that are doing better -- only one infant mortality so far after a couple of years. Come to think of it, I do have a base up installation in the laundry room, and it's in an enclosed glass globe to boot. Hasn't failed after 5 years, though of course it's not used heavily. This can be an advantage in dark areas where there are people who may not expect the light to be turned on. I agree, but not in a guest bathroom where guests feel like they're using the toilet in a cave. ;) Also, I recommend against CFLs for motion sensor lights Not only that, but they often don't work in motion sensor fixtures because they are not a 100% resistive load. That can confuse the motion-sensing circuitry -- I know it did on mine, so I had no choice but to use an incandescent. |

That can confuse the motion-sensing circuitry -- I know it did on mine, so I had no choice but to use an incandescent. That's strange. I would expect the motion sensing part to be unrelated to the load. I would think it doesn't see the load at all, until it turns on, and then it should work with any load. Motion sensor lights often rely on electronic switching means that I suspect requires the load to draw current both significantly exceeding zero and in the same direction as that to be motivated by the line voltage whenever the motion sensor electronics give a turn-on signal to the usual triac. Much of the time, an incandescent load in parallel with the compact fluorescent load fixes things - although this is not guaranteed. The triac may be triggered by motion sensing at a moment when it will have to spend possibly 1/20-1/10 of a millisecond conducting ballpark 100 amps to charge up the filter capacitor in a usual electronic-ballasted CFL, or in the case of a magnetic ballast deal with unfavorability to current flowing in same direction as applied voltage early in a half cycle when a half cycle is defined by/within applied voltage. You may get away with it, sometimes, or maybe for some significant amount of time - but usage of electrical equipment in ways other than as directed can be a *BAD THING* should a fire start or if anything goes BLAMMO, even if the bad results that occurred during "abuse" were unrelated to "abuse" and would have occurred during normal use. For a major example, fire insurance companies may give major grief should a fire start at electrical equipment being used other than as directed, even if the electrical equipment in question went BLOOEY for a reason other than being abused/misused. So, I would not use CFLs with motion sensor lights unless the CFLs are rated for use with dimmers, electronic switching devices, and the like. Heck, I would avoid usage of CFLs on motion sensor lights even if only due to low ontime per year and low ontime per start - both of which disfavor economic advantage of most CFLs, and 1 of which (low ontime per year) disfavors economic advantage of all CFLs in most locations and most CFLs in at least pretty much all locations. I favor CFLs and I light my home with them, I like them, but I feel that exaggerating their favorability works against them due to exaggerations being known by enough people to be significant enemies should enough be offended by exaggerations. - Don Klipstein ) |
