We’ve removed the driver, meaning the end user can save money by using their existing 600w digital ballast. When connected to a 600w digital ballast and mounted at 15cm above the canopy, the Adjusta-Watt® Retro LED produces an average PPFD of 1231μmol/s/m². That’s over twice the growth light than that of a 600w HPS, for the same power consumption! (required 600w digital ballast separate)

Full Spectrum LED Grow Lights

If you are interested in horticulture and hydroponic gardening, you will want to know that one of the easiest ways to grow healthier plants that are the optimum size is to simply replace your old 1000W HPS (High Pressure Sodium) lights with full-spectrum LED grow lights. The addition of blue light in the full spectrum LED grow lights means that your plants will have stronger leaves and stems. Because LED grow lights are more energy-efficient, you will not have to change bulbs as often. Your LED lighting technology will allow you to use the same lights through all phases of growing your plants saving you both time and money.

Dynamic LED Grow Lights

Growers will find some LED grow lights have useful features that will allow you to have much more control over your indoor plants. There are dimmable products and others that provide temperature safely control. Yet other LED grow lights provide sunrise and sunset settings. The light from an LED bulb shines straight down onto your plant. There is no other type of lighting system that provides more usable light to your indoor plants, this will increase plant growth substantially.

Why Choose LED Grow Light Kits?

Full Spectrum LED grow lights and LED technology may offer several benefits to horticulturalists.


Simply put, LED grow lights provide the maximum amount of energy efficiency because they produce more light and less heat. LED lights do not heat the air the way HPS lights do because they do not produce infrared light. This helps with temperature control as you work on growing your indoor plants. The fact that they produce little heat provides a secondary benefit, which is that LED lights reduce the risk of a fire in your growing space or greenhouse. The electrical power that is used by an LED is converted into a mixture of light and heat. If an LED produces more light for a given amount of electrical power, then it must also produce less heat.

Long Lifespan

You can expect your LED grow lights to last from five to eleven years. Compare this to the single year you may get out of your HPS lights and it is clear how switching to LED lights will save both time and money. Another great benefit of LED lights is that they use less power.

Superior Spectrum

Seasoned growers know that plants do best under a full spectrum of light to stimulate photosynthesis. If you are using HPS bulbs your plants are getting mainly the orange and red part of the light spectrum. Switching to Full Spectrum LED lights allows your plants to get the benefits from blue, cyan, green and yellow as well as orange and red. This full spectrum is necessary to support plants in every stage of their growing cycle, helping to provide higher yields as it’s closer to natural light. You may have heard that plants cannot use green light, but this is just a myth. Green light can be absorbed past the top of the leaves, helping your plants to produce specific compounds.

Upfront Costs vs Long Term Savings

If this is your first time purchasing LED lights for your indoor plants, you may balk at the cost. Remember, the savings will come back over time because LED lights are much cheaper to run and will not need to be changed as often as fluorescent or incandescent lights.

LED vs HPS Lights

There are several differences between LED and HPS lights. The biggest difference for growers to recognize if how they convert electricity into light and heat. HPS lights convert electricity to light and heat which may heat your grow rooms too much causing distress to the plants and in the worst case, fires. LED bulbs use the same energy to produce light and much less radiant heat.

The make-up of the lights is different as well. HPS lights are created from a ballast, lamp and reflector. LED lights are powered differently using LED emitters and a driver often within a single fixture.

HID (High Intensity Discharge) grow lights are often thought of as a cheaper alternative to LED.
