Customer Reviews

Good timer
We purchased one of these four years ago to control our entry lights. That was the last time we touched it. The unit asks you to set the turn on - off times, and set the time and date when you install it, then you really don't have to do much else. With the auto adjust feature, it resets for daylight savings time, and one setting will automatically turn the lights on when it's getting close to dusk, then off at your preselected time - nice if you don't want to install a photocell or manually change start times throughout the year.

My only complaint is that the LCD screen is very small, particularly showing day of week, which means when you do decide to change times you'll have to really squint to see what you're doing. But fortunately, for most, this won't be a regular event.

Will upgrade with ST01C model soon
Pros:
- easy to install
- works
- looks good
Cons:
- CFL lights work only with a regular incandescent added. Otherwise lights keep flashing all the time and run hot even if they are off. I use 40W incandescent light to save cost which produces marginal amount of light. Apparently, timer tends to produce power spikes since I have replaced the incandescent light 4 times in 2 months period
- ST01C Intermatic timer which Amazon sells for $29.99 can control CFL and heavy loads, so even for $10 less it isn't worth to buy this one

So Far, So Good
After going through three Intermatic SS8Cs in three years, I gave up on them and bought one of these. It's only been in a month so I can't speak to its long term reliability, but so far it's been working better than the SS8C. It's quieter - no mechanical switching (I guess it must be all electronic), it offers all the same programming options as the SS8C, plus it looks a bit sleeker on the wall. Not only that, it's cheaper than the SS8C by about $14. I did take off one star, though, because it's not DST 2007 compatible. I had to turn off its built-in DST feature and now I'll just manually spring forward and fall back.

Regarding compact fluorescent bulbs, last night we bought eight 40 watt-equivalent "n:vision" brand soft white compact fluorescent bulbs (9 watts, 550 lumens, green and white package) from Home Depot and installed them this morning. I was concerned they might not work since the packaging says the EJ500C is not compatible with compact fluorescent bulbs, but happily they do work absolutely fine! I took down eight 60 watt bulbs and am now saving 408 watts of electricity. The only thing I can think that might not make the EJ500C work with compact fluorescent bulbs is that it supposedly requires a load of at least 40 watts, so possibly too few compact fluorescent bulbs might not be enough of a power draw. For me, though, I'm happy to be saving electricity and hopefully I've got a porch light timer that will stay working more than one year.
