Dimmer/Lighting question


Hey,

I am curious...I put in a dimmer with a slider on it and 13W dimmable CFLs for the switch...

My reasoning for this was that the lights shine right on my nice 47" LED tv...

Anyways the problem is that the variance between high and low from the lighting isn't a whole lot....I would prefer the lights be dimmer at the base of the switch and brighter at the top...

Is this something that can be fixed w a higher/lower wattage lightbulb?

And which way would I go if that's the case?

Thx!

I believe you need to have a specific dimmer that is made to work with CFL and LED lights. I'm not sure if you have one of those, but that is probably why you're not seeing much change in the light intensity.

I have satisfied that need as I have dimmable CFLs in there I just am not seeing as large a variance from high to low as I would prefer...that's why I ask lower or higher watt which would make a bigger discrepancy in the switch

No. You need a dimmer specifially for CFL's, a dimmer that is for incandescent lights doesn't always work properly for CFL's or LED lights. You likely have the wrong type of dimmer installed, and that is why you're not seeing the lighting difference that you desire.

Ok maybe I should clarify...they are ok for that on BOTH ends...I have a CFL dimmer AND dimmable CFLs

Dimmer/Lighting question


Nothing you can do. CFL are only capable of dimming to something like 50% output. They have to maintain a arc to keep the gasses fluorescing and thus they never dim as much as you would like. That and most of them make a hum that is quite noticeable.

LED bulbs might do what you want but you have to pair your dimmer up to bulbs that work with it.

Dimmer/Lighting question


Not sure. some dimmers have a dial on them that adjust the max or min (forget which) but i'm guessing you dont have that either or have already adjusted it. I'm not sure how much you can dim a CFL. That may be whats the limitting factor instead of the wattage. Did you try putting an equivalent regular bulb in it and see what the variation is on that one. I think most incandescent bulbs can go from very low to full bright on a dimmer so it may just be a limitation to CFLs. Sorry I can't give better feedback. There's some notes on issues with dimmable CFLs here... http://www.1000bulbs.com/pdf/dimmable-cfl-notes.pdf

Dimmer/Lighting question


Grabbed the regular bulbs and they work like a charm...

Must be something w the CFLs that only allow a small variance to be pushed from the dimmer...

That said I will be sticking w the regular bulbs in that light until some genius out there comes up w a better way :-)

Thx for the help!

If you want lights with a large varience in intensity,
Then CFLs are not the best choice,
Stick with incandesants.
Or try using LED lamps,
the advantage is less heat.
LED lamps can be purchased quite cheap on e bay.
If you get them out of hong kong they are cheap as !
But you might have to wait for the postage,
But they are so cheap you can buy lots.
I purchased MR16 LED lamps 4 x 1 watt led
for $1.50 each thats real cheap.
