This 600W hydroponics lighting system represents the best value grow light. Its advanced integrated electronic ballast supports both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs, giving the grower the flexibility to choose the best selection simply by changing the bulb, instead of having to own two separate light systems.MH is used for accelerated vegetative growth, then switch to HPS to encourage flowering, fruiting and budding. Reasons to Choose Digital Electronic Ballast: ? Fast startup - reaches full brightness in less than 1/4 the time of most magnetic ballasts ? Completely silent - no more of the humming and buzzing ? Small, compact design - most electronic models weigh less than 10 pounds compared to 44 pounds for magnetic ballasts ? Longer bulb life - lumen output loss over time is dramatically less than with magnetic ballats ? Electronic ballast lights both MH and HPS lamps ? More lumen output - up to 20% more lumen output than regular ballasts ? Heat sink technology - no fans to break down and make noise; fan-cooled ballasts have a higher failure rate Features: ? Electronic ballast (600W) ? Includes one High Pressure Sodium (HPS) bulb (600W) and one Metal Halide (MH) bulb (600W) ? Electronic ballast works with both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs ? Electronic ballast is UL listed, CE certified ? Two-year manufacture warranty on electronic ballast ? Quality light reflector ? Power cord included ? Lamp cord included ? Discreet packaging Light Fixture Specification: ? Fixture Size: 18.5-Inch x 15-Inch x 4.5-Inch ? Total Weight: 19 Lb

Getting Your Own LED Grow Lights Kits
LED grow lights are all the rage now if you are interested in or already growing plants indoors. The reason behind this is the host of advantages that these grow lights have over other more conventional technology. In addition to this, the benefits of these lights are enhanced more and more every time there is a new breakthrough in the science behind it and they are made more effective than before, in every way possible.
There are many different types of LED lights available on the market today. It doesn't matter if you are just about to start panning out your interest in growing indoor plants for the first time or if you are a seasoned veteran in this field, there is something to suit the needs of everyone. If you want to build your own 12V grow light, then you can easily buy kits which are designed to help you do just that. Always go for a high quality product so that you can take advantage of all the great features of grow lights.
A good quality kit will use only 256 high brightness 5mm LEDs. It will also use up only 16 watts or 1.4 amps worth of electricity, and at the very least should come with a guaranteed life of up to 100,000 hours. This basically means a life of a minimum of fifteen years if used for 18 hours a day, every single day of the year. In connection to this, you should ask in advance where to get a replacement in the case that your LED burns out. A plus point would be if the grow lights worked with very little or no noise at all. Ideally the lights should measure 5.9x5.3x0.5 inches all around, and the home board on which they are to be mounted should have evenly spaced out holes on the outer dimensions to ensure uniform heating and light.
In the same way, you can get a 14 watt kit to set up your own 120V light. A good quality kit will be one that utilizes 272 high brightness 5 mm LEDs with 204 red ones and 68 blue ones. The dimensions should be in the proximity of 6x4.75x0.5 inches. Also go for a kit that has an active current regulation circuit. The reason for this is a greater control over the product than provided by resistors in all their capacity.
You can now also easily get 100 watt grow light kits from retailers, both online and off. Good product kits will feature Xlamp high power LEDs, with at least 40 red ones and 16 blue ones, and a minimum power delivery of 100 watts with never a power consumption of more than 125 watts. Always check to see what the lifetime of the LED grow light is said to be; ideally, there should be around 50,000 hours guaranteed. There should also an integrated power supply that doesn't need a ballast to work properly.
