Help with: Dimmable Compact Florescent Bulbs
Sometime lurker first time poster.
As some of you may know, I wanted a very bright play area for my unique kids room basement project.
I purchased a pilot number of these: GE R30 Compact Florescent Lamp (CFL)
They claim to dimmable. From the package “works with most dimming switches”
They work very well on a regular single pole configuration.
I believe them to be of type: Magnetic Low Voltage MLV – CFL.
I purchased this dimmer from Lutron Maestro the only where it said it was for incandescent was in Spanish so I missed it. While it is clear that they make types specifically for MLV, this dimmer seems pretty “standard” to me. So,as you may have guessed, it didn't work.
So, I returned to my favorite money sink: Lowes and purchased a different model of dimmer that specifically, on the package, said is was for Magnetic Low Voltage-type devices. It was of the type Cooper Wiring Devices ASPIRE™ Slide Dimmer
Hooked it up and guess what? It didn't work either.
So I said “:censored: this, to hell with the environment” and hooked up the original Lutron dimmer back up and started counting the number of regular incandescent fixtures I would need.
It was dark, no lights duh, and I replaced the first of 6 lights with an old incandescent I had.
Here is where our story takes a twist: All the lights came on. In fact, the incandescent worked correctly and the CFLs dimmed to some degree. :huh:
You should know that I had a professional wire this system and the CFLs work on a regular switch and also the dimmer works with regular bulbs. (scientifically tested.)
Magnetic low voltage dimmers are not really designed for CFL applications. MLV dimmers are for low voltage fixtures that have magnetic transformers. Dimmable CFL's should work with a standard dimmer. I would reccommend trying to start the fixtures at full bright and work your way down.
This is reason #45 in a long list of why I hate these lamps.
They do say to turn them up to full power, then to dim
I don't mind the CFL's at all
But I only have 4 dimmer bulbs so far & they work
compact fl.= JUNK
I don't think so
Kitchen used to use over 300w & light was poor
I switched to CFL & now use 65 watts if the 5 main lights are on & the light is excellent. If we turn the hockey puck lights on we use another 4w
I use a LOT less electricity on lights then I used to
My bathroom light no longer shuts off due to the heat sensor
Since the 23w cfl puts out the equiv of 100w light bulb but NOT the heat
Bathroom used to use 220 watts
Now I use 52w & thebathroom is MUCH brighter
I have over 200 cfl bulbs in my christmas display which saves me about 8,000w an HOUR
And MOST of them were FREE after instant coupons at Home Depot :thumbsup:
CFL's ROCK :thumbup:
cfl= mercury in landfills
Max is a 100 watt bulb
It shuts off with a 100w bulb
So you are wrong about that
CFL's = less mercury in the environment, it's a proven fact
CFL's are MUCH better then incandescent
Until all the problems are worked out with LED's , overheating & electronic issues they are the best bet for the $$
LED's - one person lost all 3 after a lightning storm
They are not lifetime bulbs, they can & will burn out
LED's are the future. Of course they are expensive. Of course they burn out, but the downsides are small compared to the problems with CFL's. I hate the color rendition, the mercury content (small but present) the start time, the flicker, and the dimming issues. I don't think we'll really see widespread LED applications for resi in the very near term but it is coming.
If you want to see some really next level stuff, check out OLED's. I've seen one of them. Picture a 2 x 2 fluorescent fixture that is about 1/4" thick. The TV's are pretty incredible too. So thin you can bend them.
Well I don't know where other people buy their CFL's
But I've bought NVision, bright effects, GE & Sylvania & do not have any problems
That includes 200 in cold weather in my Christmas display
Once incandescents are "banned" then LED & CFL's sales will increase. Until LED's come down in price the vast majority of people will not buy them
It's unfortunate that the Utility Companies/Govt will not push the LED rebates as much as they are pushing CFL's. I can buy a 4 pak of CFL's for less then $3. That's what I used to pay for incandescents years ago. The last 4 pks of of incandescents I bought were .42. With the economy the way it is people will buy the least expensive product
Until LED's come way down in price I will not even consider them
I have 3 LED hockey puck lites in the kitchen & LED rope light (clearance) Plus LED night lites (clearance)
I have been switching my Christmas display over to LED
But switch-over that stopped in 2007
Dave, I agree that cost is a concern. How do you like your LED rope light? I considered buying one, but I was worried that the light was going to appear blueish. What was your experience?
The rope light is pretty good
We use it after dinner to light the kitchen
It uses about 10 watts for 18' length
I bought it on clearance - I think 75% off
It's 1/2 wave rope light & there is a little flicker to the light
But its a crisp white light - not blue & not yellow
I also have a sting of LED christmas lights on the front 3 season porch as a nite light. They have been running on a timer for 3 years now
One problem with LED lights you can run into is "flicker"
Full wave lights do not flicker
1/2 wave lights do flicker
I'm pretty sure most of the LED bulb Mfgs make their bulbs full wave
But when you run into Christmas lights & rope lights the lower cost ones are 1/2 wave, not as bright, & will have flicker
Many people will not notice this flicker
But some people will, & some it will really bother
Full wave strings have a part of the electric wire that looks like it swallowed an AA battery. I'm not positive of the name but I think its a rectifier?
Its a standard 100w light bulb
Its not a recessed can
