Testimonials



We have 7 shopping centers in 2 states. We upgraded the outdoor lights to LED’s three years ago and our contractor installed GPS LightLock. Our property managers haven’t had to call an electrician since.
We're saving money and we love it.
Thanks GPS LightLock!

This place had 50 photocells when I started here 10 years ago. Everyone complained the lights switch all crazy. We tried $600 timers and they were so bad we put the photocells back in. Then we found GPS LightLock. They're perfect.
MC, Electrical Sup’t., Bonita Springs, FL

They are working out perfectly and as advertised. I have tall trees which shade areas of my property where the ordinary photocells did not turn off until 11am and turned on at 4pm. This was wasting energy, money and looked suspect that nobody was home. So your gps timers helped with my security of my property.
Thank you!

When we had to change out a programmable timer, we had to go to the supply house, spend $400, come back and rip the guts out of the old one, rip the guts out of the new one, put the new guts in the old housing, make up the connections, and … geez - it took half a day.
With this thing, it’s bam- done! Under a minute.

I now have all of my present exterior lights controlled by GPS lightlock.  I am waiting for the Township to do the installation that will put the illumination of our township clock under control of your product.
Great product.

Love the timers. I am installing them in lights at our church. Far superior to other timers. Will buy more as I can install them.
Thanks.

I just returned from a Township Committee meeting and am happy to report that the 19th century clock is now illuminated by a 21st century light control system.
