HTG Supply 150 Watt HPS GROW LIGHT:

The #1 line of grow lights in the USA — HTG Supply value series grow lights are preferred by thousands of indoor gardeners across the country for their rock-solid reliability and versatile design in addition to their economical price. A logical remote system configuration allows HTG ballasts to be located outside of the grow area to mitigate excess heat, and the unique split-cell housing keeps ballast components cooler for extended life and improved performance.


Dimensions: 9″ Long x 4″ Wide x 5.5″ Tall

This premium HTG SUPPLY GROW LIGHT ballast and components are housed in an ULTRA-EFFICIENT OPEN AIR BALLAST HOUSING. Unlike other enclosures that house their ballasts inside a metal box – causing heat build up and lowering component life and performance – the HTG SUPPLY GROW LIGHT ballast housing incorporates an OPEN AIR type enclosure. The housing is actually built around the copper coil ballast allowing for the heat generated by the ballast to dissipate quickly and efficiently. The #1 killer of electrical components (like the ignitor and capacitor) is excessive heat. Components such as the ignitor and capacitor are housed away from the ballast inside their own small enclosure, thus keeping them cool and away from the heat generated by the ballast itself. This ballast enclosure design is time-tested in industrial/commercial H.I.D. applications worldwide, but THE HTG SUPPLY GROW LIGHT is the ONLY GROW LIGHT to incorporate this intelligent, simple, and efficient design. The OPEN AIR design of the HTG SUPPLY GROW LIGHT keeps the components cooler than any other system on the market today! The remote ballast design is far superior to other designs found on eBay and other sites.

Includes 10’ grounded power cord that plugs into a STANDARD HOUSEHOLD OUTLET!


This top of the line HORIZONTAL REFLECTOR is made from the HIGHEST QUALITY MATERIALS available! Specifically designed for growing plants, this reflector incorporates a steel socket/reflector bracket, 5kv Pulse Rated Mogul Based socket and highly reflective polished aluminum reflector. The highly polished aluminum reflector has a mirror-like finish rated at 95% reflectivity for MAXIMUM LIGHT OUTPUT. This super reflective surface provides more raw light output than dimpled reflectors and is far superior in reflective qualities than cheap white painted reflectors which discolor over time. Polished Aluminum will NOT RUST, CHIP, or CORRODE like inferior chrome reflectors do under the intense heat of a high-intensity discharge (H.I.D.) bulb like the High Pressure Sodium (HPS) bulb that comes with this system. This reflector is built to last a lifetime, and can easily be cleaned with common household window cleaner. Horizontal lamp configuration design allows for the greatest light coverage over the top of your garden area while providing the highest light intensity levels possible. It is widely recognized that the BEST design for horticultural reflectors is the HORIZONTAL REFLECTOR design incorporated with this reflector. The reflector comes with two heavy-duty steel hangers to hang your reflector from, and the cord from the reflector to the ballast housing measures 10’.

Reflector Measures Approx: 16″ Long x 13″ Wide x 6″ Deep


Brand new HIGH OUTPUT 150 watt High Pressure Sodium bulb is rated at 16,000 lumens! Life expectancy is 24,000 hours. 22 CRI. The 150 watt HPS bulb is a very popular bulb used by the indoor hobbyist grower today. The 150 watt HPS is more efficient in producing light than its Metal Halide counterpart and also features very little lumen loss over its lifetime compared to Metal Halide bulbs. You can expect only a 10% decrease in lumens over a bulb’s 3 year (24/7) lifetime. Compare that to Metal Halide, where there is as much as a 50% decrease in lumen output over its shorter lifetime and initially lower light output than HPS, and it is clear to see why the HPS is so popular. It is believed the HPS bulb’s bright “yellowish” spectrum mimics that of the “harvest sun”, triggering plants to develop flowers rapidly and abundantly. You can expect excellent results using this HPS bulb, and it is good for ALL STAGES of PLANT GROWTH!



Warranty for this system is 2 years on the ballast and components and 1 year for the bulb. Remember, this is simply the warranty. This system should provide ten, even twenty or more years of reliable service.
