Compact Fluorescent Lights

Flood alternative
Last weekend I did a survey of my light fixtures at home and bought enough compact fluorescent lamps (CFL) to change nearly all of them over from incandescent. I’ve had a few CFLs in the house for a while and learned early on that paying for the good name brands results in lamps that last much longer and is worth the extra cost. I bought the GE brand because of the wide range of shapes, wattage, and colors available. I learned a few things this time around. You can get a lot more light out of that bedroom ceiling fixture with CFLs than you can with incandescent while not exceeding the power rating of the fixture and still use less energy. Some of the squatty globe style ceiling fixtures may require a smaller CFL form factor than you would like to use. The good news is that when you break a 23W CFL trying to make it fit, all of the glass and mercury is caught by the globe. I have a lot of X-10 switching in the house. It seems that the 3-wire X-10 equipment has no problem with the RF interference from CFLs. The two-wire switches can be a problem though. I have only one circuit, in the garage, that is problematic and I’ll follow up when I have a found a solution. The so called full spectrum (5700K) lamps are pretty blue and the warm white (2700K) lamps are very yellow at the lower wattage. The high wattage warm whites are much less yellow. Finally, I have yet to find a CFL spot or flood lamp that comes on bright when first turned on. They start out very dim and take a minute or more to approach full brightness. This can be good or bad depending upon what you need. In the master bath, I turn one of those on first in order to let my eyes adapt slowly. I like that a lot and I don’t need a lot of light when I am er… umm… sitting down for a while, however, in the kitchen I want those spots to be bright immediately. I found one lamp that is made of a conical spiral tube that works better as a flood.

Joe,
As you may or may not know, I have many fixtures using fluorescent bulbs for YEARS, so I actually have very few incandescent bulbs in my house.
However, I have retrofitted some of the table lamps (years ago) with the fluorescent technology of the day and have found them lacking in several ways.
Recently though, while strolling through one of the local big box home stores. One particular display caught my eye because it had a bright, white CFL lamp/bulb in the array of demo bulbs and it was fantastic! Good color and plenty of different wattage selections to choose from!
As I had already converted my regular florescent fixtures to daylight (or, near-daylight) lamps, I’m ready to make the switch throughout the rest of the house. Just as soon as I get through approximately 100-years worth of incandescents lying in the basement warehouse
More than likely though, I continue holding out for the LED equivalents to drop in price before going crazy again and doing a wholesale switch out.
BTW, 90+% of all of my flashlights are already LEDs and the new LED lamps and sockets are on hand for next year’s deck upgrade

Hooda,
I have a big box of slightly used incandescent and halogen bulbs that I hope to save to eventually sell on eBay one day – long after they have been banned. If only I could find a compact form-factor CFL for use in my foyer chandelier and porch lanterns.
LEDs are coming along, but their lifetimes are very short if they overheat. The expensive LED lamps are mostly heat sinks. I’m going to hold out for OLED sheet lighting.

Joe,
What if FleaBay suddenly develops a social conscience and bans the incandescents?
Okay, I’ll bite, what are OLES sheet lights; I’m a bit behind on reading my technical journals
And, you’re right, of course, about the heat-sinking vs. usable light issues; all of the GOOD LEDs run HOT, but not for long.
The automotive/vehicular retro-fits are particularly troublesome; we see lots of them with blown segments running around.
The OEMs though, not so much.
