Great Timer

Mine has been in for 6 years without any problems. Works as advertised. No complaints.

Older versions great, not sure about latest ones.

I have used these for years with no problems. Purchased 2 more a year ago. One has failed recently, failing to turn the light completely off. Checked all wiring and found nothing wrong.

It is a good and sturdy switch.

I have owned several over the years. They are dependable. Programing them is confusing however, because AM and PM not marked.

Is this Intermatic timer available in ivory, cream or almond? I only see it sold in white but I need an off-white finish.

by Gerald B. on 03-28-2015

This particular model is only available in white.

Will this timer work for 6 outside lights that are controlled by one inside switch. Each fixture has 2 bulbs. The bulbs are incandescent but may total over 500watts. ( I could reduce the wattage of the bulbs if necessary) I know that some timers turn off if one bulb burns out. I don't want that feature, it would be too difficult to figure out which one burned out.

Can I use this product EJ351C in place of my previous timer, EJ 351 ?

by Kathryn S. on 12-19-2012

The EJ351C is a direct replacement for the EJ351.

Will this switch work if I am trying to control two outside light fixtures? If not, could you direct me to one that will work? Thank You

by William H. on 08-09-2012

This will work if the switch is installed indoors, and the two outside lights are on the same circuit. AS long as both lights are wired to the switch, it will work fine. This switch is rated for 500 watts incandescent.

Is this timer heavy duty enough for attic installation? Concerned @ temp extremes during summer & winter in attic. Timer to be on supply side of Lithonia 250W metal Hallide security light currently controlled by a photo cell only. Photo cell in shade so light burns more hours per day than needed. Want to limit by having the timer only supply power to the security light during certain hours in the evening.

by Paul S. from North Carolina on 07-14-2012

Yes, this timer will work for residential attic applications. The 500W rating on this timer will be adequate to handle the 250W MH security light. In regards to temperatures, for most indoor applications, you should be fine, however, if there are concerns of high moisture / freezing you may want to install a protective box around it.
