Reduce energy consumption up to 90% for Commercial, Industrial & Municipal lighting applications, which can save thousands on electric and maintenance costs.

Solstice LED HID Retrofit

gtl 10 yr warranty logoWhether your business is a warehouse, car dealerships, parking lots, a retail center closed for most of the night, a parking garage, or an advertising sign, most likely your HID (High Intensity Discharge) Lights are the majority of your lighting costs. Typical life spans of your current HID bulbs range from 12,000-20,000 hours. From the clients we have worked with, especially the car dealerships, they are replacing components almost each bulb every year; whether it’s the bulb, the ballast, or the capacitor. Each time costing them a service charge to get up the pole and maintain the light.

This Solstice is truly an AMAZING piece of engineering! Invented by an American, Made entirely in the USA, with American engineered components, and assembled by Americans. It is UL approved for field retrofit of existing fixtures and DLC listed for rebates, GNPSOL5400 and GNP2700M. Read our Information Brochure.

This light mounts directly into your existing light fixture and utilizes your facility’s wiring. We can replace your existing Sodium High Pressure, Metal Halide, Mercury Vapor light with the Solstice LED and reduce your lighting consumption by 70-80%. The Solstice unit carries a 100,000+ hour life with independent testing proving a 200,000 hour life span.

If your facility has HID lighting, we have a Solstice that is right for the retrofit. The GNP2700M unit replaces 50W-175W light bulbs, where the 5400 unit replaces 70-1500W. In fact, we have a selector switch on-board each of our lights that allows us to select the amount of light we want to produce. We can utilize multiple Solstice units to increase the light output to match up to 1,500 watts! Read the Application Guide.

For example: Your parking lot is lit with 400W metal halide bulbs, we will replace these with the GNPSOL5400 LED. We light the parking lot with you there, the selector switch set on 94W, (true lumen for lumen retrofit). You say to us, “WOW, how can I save more?” We go up the pole and select the switch from 98W to 88W. This process could then lead down to 68W or 54W! “Not enough light there…” you say, “Can you put it back bright?” In about 5 minutes, we have proven equal lighting and then saved you much more than expected.

Additionally, we can custom program each Solstice unit to operate at various percentage output for different periods of the night. If you own a shopping center that only needs 100% output for the first 5 hours of the night and the last 1 hour for security. But the 6 hours in the middle of the night, you could live with 50% output to conserve consumption.


Our Smart-Driver Technology equips us with drivers that individually measure over-current, under-current, over-voltage, under-voltage, the operating temperature, and the individual LED chip color. This ability to keep all chips operating with the same color light from Day 1. Our programming utilizes a Safety Mode that shuts down half the chips to both alert us to a problem as well as protect the circuitry.How many gas stations, parking garages, street lights do you drive past that none of the bulbs match each other? This is evidence that the lights and the components are degrading at different rates. Our Solstice Units will never let this happen, it’s in their programming and engineering.

The Solstice LED light is programmed with a 3-stage Soft Start start-up system whereby the current is fed and monitored in 3 easy levels to protect the chips, modify color and extend the life of the components. Additionally, the LED chips are all wired in parallel design where they all receive equal electrical current at same time. Other LED lights on the market place their chips in series where the first LED chip of the Daisy-chain is hit by all the current every night.

The #1 enemy of electronics is heat. Heat degrades the components over time. Our Solstice LED head is engineered to dissipate heat two ways. First, through the 7-layer copper heat-sink, heat is removed from the LED board and channeled away. Secondly, a MAGLEV 100,000 hour cooling fan is mounted to the rear of the unit to circulate air within the fixture. This can properly maintain an operating temperature 25 degrees cooler than competitors. These cooling measures translate directly into life spans more than twice as long. 200,000 hours are now within reach!

How long is 100,000 hours?

Based on how long a fixture is illuminated per day, here’s what 100,000 works out to:

Hours of Operation:

24 hours a day
18 hours per day
12 hours per day
8 hours per day

100,000 hours is:

11.4 years
14.8 years
22.8 years
34.2 years

We replaced a 1000w MH Highbay with our retrofit. We reduced their consumption from 1100 W to 250w! We also increased their foot-candles on the ground by nearly 20%!


Not all LED Lights are equal.

In fact, so many LED lights on the market are over-priced, over-marketed, foreign-produced, under-delivered, under-lit, and under-warranted.

Our lights can be retrofitted into YOUR light fixture without major modifications, with either the yoke which screws into your existing Edison base, or our plate mount kits.

Don’t replace your current fixtures

Our LED lights fit right into your fixture; we utilize your wiring and can be programmed to your needs. By adding our wireless control system you can control and program for dimming, motion, light sensors and have complete ease of control.
