About the system:


Your search has ended! You have found IT here on !

You'll find this grow light in literally thousands of gardens nationwide. It outsells all other models of grow lights hands down. With well over 15,000 units sold to date, this light has a proven track record of reliability and results. Available only from HTGSupply (online and at our retail locations) you will not find a better built, better priced brand new complete grow light system anywhere else.

The reasons for the success of this grow light are evident in it's top quality workmanship, superior design, proven reliabilityand unbeatable value and price.

This is THE grow light of choice for smart shoppers looking for quality and value.

Our reflector design is simply THE BEST! We took the best ideas of the popular"batwing" style reflector and added angled end panels so not a single lumen of light is wasted! All light emitted from the bulb is directed downwards to your gardenresulting in great plant growth and higher yields! Computer design photometrics ensures an even spread of light across the garden canopy with no hot spots. New Dimpled or Hammertoned Polished Aluminum Reflector offers the best performance possible. You get the highly reflective qualities of polished aluminum (it's a mirror like finish) with the superior light dispersal from the dimpled/hammertoned finish.

This reflector is worlds ahead of older style "batwing" reflectors seen elsewhere.

Measures approx: 15.5" Long x 12.5" Wide x 6" Deep

The design of our ballast housing keeps heat generated by the ballast core away from heat sensitive components (igniter & capacitor). This is the same concept design that you'll see that the high priced grow lights now feature! You should know that WE were the FIRST to offer this design and it is now widely accepted as the BEST design for grow light ballast housings!

Our ballast housing also has a convenient handle making it easy to pick up. The handle features KEY HOLES for mounting on a wall or ceiling. This feature has been very well received by growers nationwide!

The HTGSUPPLY grow light plugs right into your householdgrounded wall receptacle. We provide a top quality three prong grounded plug and heavy duty 10'power cord to all our grow light systems. The ballast to socket set / reflector cord measures 10' long and issuper heavy dutyand ratedfor the high electrical currentdelivers to the lamp. This attention to detail is evident in our grow systems and is lacking in other systems in this price range.

We've thought of everything when we designed our ballast housing. Oversized Rubber Feet provide electrical protection and keep the ballast up off the floor away from spills and other hazards. Their large size ensures that any ballast vibration is absorbed by the rubber feet providing ultra-quiet operation. This is a feature that even the most expensive ballast housings overlook.

It's details like this thatshouldtell you that this is not an "economy" grow light. This is a PREMIUM GROW LIGHT SYSTEM for sale at an economy price!

High Output Spectrally Enhanced 400 watt High Pressure Sodium (HPS)Grow Bulb emits 55,000 lumens of plant growing light! This bulb is head and shoulders above standard 400w HPS bulbs. It emits 10% more light than standard bulbs and also has an increased 30% violet/blue spectrum which encourages photosynthesis. This is THE perfect bulb for optimum plant growth and flowering!HPS bulbs are known fortheir excellentlumen to watt ratio, meaning they emit a lot of light for the amount of electricity they use.With our high output bulb you can equate a 10% increase of light output directly in 10% more plant growth! HPS bulbs are also very high in the RED lighting spectrum which encourages flowering/budding but also causes stem elongation and long internodes (the space between branches). With our bulb he 30% more violet/blue spectrum means plant will grow better andmorelushdue to the more balanced light spectrum. This bulb really packs a punch and has been specifically engineered for plant growth.


The HTGSupply grow light is the ONLY grow light in this price range that offers a removable universal socket set. This allows you to easilyremoveyour current reflector and UPGRADE to different reflector if you ever desire to do so (like getting one of our air cooled reflectors).It also allows you torun the 4" socket set through awall or partition to keep the heat of the ballastout of your growing area (a ballast typically generates about 15% of the heat of a grow light system with the loin's share coming from the light bulb itself). Super convenient wing nuts do not require any tools to remove or tighten It fits all of our available reflectors pictured in the links above and also fits many other name brand reflectors as well.


You will have fast growth and exceptional yields using this light for your garden by using these guidelines for the size of your garden. A common question is "how many plants can I grow with this light?" The answer is not given in the number of plants but rather the size of your garden area. As many plants as you wish to fill your garden and what types of plants you wish to grow is up to you. The wattage of your light dictates the size or area of gardenyou can grow.

This 400 watt system is the perfect size light for garden areas measuring anywhere between 3'x3' to 5'x5' square feet. Square footage is measured by the floor space below the light where you garden is located. These figures represent the amount of light needed for optimum plant growth for plants that have high light needs. Most all plants including vegetable and herbshave high light needsand some exceptions aresome types of Orchids and other exotic plants excluded.

As you can see, the HTG SUPPLY Grow Light system has many attributes including:

-Top Quality BRAND NEW Ballast, Components and bulb!

- Innovative Open Air Ballast Design keeps critical components away from the heat of the ballast ensuring a long, reliable life span for this system. Better than the rest, it's like nothing else out there!

-Superior Ballast Design including a Retractable Handle with Key Holes for wall or ceiling mounting

-Oversized Rubber Feet that provide electrical protection and ensure quiet operation

-10' Grounded Power Cord that plugs into a standard household outlet.

-Heavy Duty ten feet long 14 gauge Ballast to Reflector Cord

-Universal Socket Set that fits MANY other reflector types allows you to use different reflectors if you so choose. This allows you to go with an Air Coolable or any other type reflector in the future if need be - it's UPGRADEABLE!

-Ultra Efficient Four Sided Horizontal Reflector for unsurpassed performance. This reflector is simply the best of it's kind in bothperformance and quality.

- High Output Spectrally Enhanced 400 watt HPS HORTICULTURAL GROW Bulb. This bulb is specifically designed for Plant Growth, not some cheap run-of-the-mill bulb others offer.

- Warranty for this system is3 years on the ballast and components and 1 year for the bulb.You will not find a warranty like this for a value priced unit anywhere!
