Heath Zenith SL-6107-WH Motion Activated Wall Switch

Bought Two - Seeking a Model that works better with CFLs (2010-07-11) : 3/5
I purchased two of these -- in the kitchen where I have one (CFL) fixture it works great. Downstairs in the basement I have 5 CFL fixtures and on automatic the lights buzz when on, and flicker when the motion sensor would have them off. I got a GE motion sensing switch too, which exhibits the exact same behavior downstairs. (The 'on' and 'off' positions work great.) I would love if anyone could recommend a motion sensing switch likely to work with larger clusters of CFL bulbs.
Love it (2010-06-02) : 5/5
Use it in the bathroom for a single overhead light, with the vanity light on a switch. Sensitivity and reaction time is great (although not adjustable). Being able to adjust it to not come on based on ambient light is also a great feature. Fixed settings for timer (e.g. 1min, 5min, etc.) would be nice if you could adjust for whatever you wanted. Overall though, does exactly what I want and works as described. Continuation of my good experiences with Heath Zenith products.
Good with incandescent bulbs (2010-05-26) : 4/5
I installed one in the garage with 4 fluorescent bulbs, lots of flickering. Moved it to be used with incandescent and it works fine. I'm just sad it didn't work well in the garage.

I love this thing, easy to install, easy to use. The main resason I got this was my child would leave the lights on ALL THE TIME. With this they go on by themself they go off by themself. You can adjust when they go on (due to outside light), and how long they should stay on. They do work with energy saver bulbs. I have had these installed for about 30 days and I would recommend them.
Multiple serious problems with this unit (2010-04-11) : 1/5
There are multiple issues with this switch.

1.) Does not work with many CFL setups. The amazon description indicates it works with "up to 400W" of fluorescent lights. If you read the fine print in the manual that comes with the switch, it only works with rapid start ballasts and needs a minimum of 60W of fluorescent lights to work correctly. I tried the unit with a single 26W CFL and when the switch is in "auto" mode, the light continuously flickers on and off even when there is no motion and it is supposed to be off.

2.) The "time on" feature doesn't work right. The instructions tell you to turn the "time" screw until it snaps into place at test, 1, 5, 10, or 20 minutes. The screw does not snap at all. I turned it to 5, and the light still went off after about 15s. I turned it to 20 - same thing. In fact you can just keep rotating it indefinitely. Eventually, by playing around with it for a few minutes I got the delay to increase up to several minutes, but I'm not sure why or how. I thought maybe my unit was just defective, but I bought two (from two different stores) and both did the same thing.

3.) If you switch it too quickly between on/off/auto modes, you can get it hung in an auto mode where it just flashes the light on and off. I was able to replicate this problem on both switches that I bought.

4.) The auto mode never really turns the electricity off. You can tell, because if you throw in an LED light, when the auto mode goes to turn the light off, it just dims. So you are basically wasting a small amount of electricity even when the auto mode turns the lights "off."

5.) The "off" setting doesn't turn the electricity off either! This seems like it could be a safety hazard. Again, if you throw in an LED light and turn the switch to "OFF," the light dims slightly more than when the auto function turns it "off," but still doesn't turn off. Believe it or not, even when you turn this switch to "off" you are wasting electricity.

6.) Obviously, based on #4, and #5, this unit will not work with LED lighting.
