Signaling & Pulse Timers
Photocell Integrated Timers
Day of Week Scheduling Timers
Run Time & Relative Run Time Timers
Calendar & Seasonal Scheduling Timers

Extensive New Timer Scheduling Capabilities

Combine any or all of the following to meet your requirements.

Astronomical Time to switch relative to Sunrise, Solar Noon, Sunset, Solar Midnight and any offsets therefrom.

Local Time with scheduling up to 30 intervals per day with or without automatic daylight savings time.

Dimming Control for 0-10V Dimming, PWM Dimming or PWM Waveform Signal.

Photocell Integrated where we couple the timing output to an encapsulated
extra-long-life ceramic based mil-spec photocell.

Run Time or Relative Run Time to run for a defined period relative to on time.

Calendar Scheduling for day of week, seasonal control, holiday scheduling, etc.

Signal Pulses to sound a bell, tone or other signaling device, or to initiate or terminate a process.

Priority Scheduling for example when you want lights on from Sunset to 11pm and then again from 7am until Sunrise, but at certain times of the year Sunrise may come before 7am in which case we assign a higher priority to have the lights off from Sunrise to Sunset.

How It Works

GPS Timers have factory hard-coded programming making every unit we sell plug & play right out of the box. This means they are self-programming & self-recovering from power outages without human intervention for the life of the product.

At power up your GPS Timers will obtain a latitude, longitude, date and time sync from the GPS Satellite System which is then loaded into a secondary microprocessor where it becomes the basis of your switching schedule for the life of the product.

Your systems will switch on time every time and we guarantee it!

There’s nothing to learn, monitor or maintain. You won’t need any servers, software or network infrastructure. You can even start with a single stand alone unit and scale any size facility, area or region at your convenience.

The GPS system is always free and it’s always on.

You can also move them from one location to another because they always know where and when they are.

It pays for itself many times over in service call savings alone over the life of the product. You’ll save energy by having the most reliable switching schedule possible. You’ll maximize the full rated service life of your equipment.

And you’ll put an end to complaints about erratic & inefficient switching when you install GPS Timers.

GPS Timers are Made in Fort Myers, USA!

Great product. Very well designed.
Matt D, Cont. Maint., Baltimore City Schools

We have had excellent results with the LightLock units. Thanks for introducing this product to us.
David Z, District Maintenance Supervisor, Orange County, FL

We received and installed your GPS LightLock products and they have been working perfectly. The synchronization between the astronomical timers has been reported as less than a second apart. Our City Electricians are happy about the plug and play, time saving functionality of the device. Thanks for making your product available in Canada.
Wayne B., Assistant Electrical Foreman, City of Winnipeg Canada.

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!
Paul & Mary R., Norcross, GA

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!
Ray B., Chicago, IL

Worked out great. Works like a charm. Been passing along the info about it to alot of different people.
Will order more soon.
Scott S., Electrical Contractor, Farmington, IN

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 it took half the day. With this thing, it’s BAM! DONE! Under a minute!
Paul S, Lead Electrician, Florida Gulf Coast University

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

David W., Waller, TX

It worked as advertised right out of the box.
William H, Saint Francisville, LA

Great product. Will buy more. Would recommend.
David C.

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.
David W. (2nd order), WALLER, TX

Great product!
David C 10/4/2015 (2nd order)

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.
Regards, Richard, NJ

Great cure for the shady side of the building
Cale R., Centerville, OH

The unit works great for our garage lighting. We recently got a second one for our landscape lighting. It's great. Thanks for a great product.
Mike M, Taylor, MI

Installed last week. Works exactly as advertised.
