Getting the LED Grow Lights Right

Indoor lights are used to substitute sunlight. Not any kind of light will do the job of a good grow light. There is a basic difference in the way we see light and the way plants utilize it. Human beings are not much affected by the color of light but for plants light color is absolutely vital. Plants harness light with the help of pigments the most common of which is chlorophyll. There are others like xanthophylls, carotenoids etc. but chlorophyll is the single most important pigment. Chlorophyll reflects green light – that is why plants appear green. If a plant were to be grown under green light it would not be able to produce any food as it won’t be able to absorb any of the light! Chlorophyll has two light absorption peaks – one in the blue region (700nm wavelength) of the light spectrum and the other in the red region (400 nm wavelength).
Apart from the basic science behind photosynthesis plants generally prefer red light prior to their flowering stage. This is because light receptors in plants are activated by light in the red portion of the spectrum and initiate a complex biochemical pathway that induces flowering in plants.

  • Larger plants need more light
  • Vegetables typically need more light while Shade plants can make do with small amounts of light.
  • Plants need both light and dark periods. The dark periods are particularly important for flowering.
  • In an indoor setting, it is the amount of light falling per square foot of surface that is important and not the amount of light emitted per bulb.
  • The unit of light appropriate for indoor cultivation of plants is NOT Lux (1 lumen per square foot) but PAR per square foot (PAR = Photosynthetically Active Radiation).
  • You can choose to have a full spectrum light source that will deliver all wavelengths of light and mimic sunlight. Alternately you can choose lights that produce only the most productive wavelengths of light (Blue and red). The advantage with the second approach is that electricity consumption and heat generation are far lower.

Grow Light Options

Incandescent lights, fluorescent lamps, HID lamps (high intensity discharge), HPS (High Pressure Sodium) lamps and LED lights are the different options that are available. Incandescent bulbs produce warm light but are so inefficient at light production that they have become obsolete for use as indoor horticulture lights. HID, HPS and fluorescent lights are used but are rapidly being replaced by LED grow lights.

HID and HPS lights produce a lot of heat. A 1000 watt lamp emits only 250 watt worth of light and 750 watts of heat! LEDs are 4 to 10 times more efficient. They let growers – professional or hobbyists cut electricity costs manifold. An added advantage is that LED grow lights last 50,000 hours or more. So there are no replacement hassles. Indeed it was this that prompted scientists at NASA to use LED lights for growing plants in space!

NASA scientists could either carry a large supply of replacement bulbs and designate one guy solely for replacing lights or opt for LEDs. Obviously they chose the latter. The facts that these lights are small, weigh very little, do not contain mercury and produce precise light are other factors in their favor.

LED Grow Lights

Low electricity costs – A 90 watt LED light based system can easily substitute a 600 watt HPS system. This is because LEDs are more efficient at producing light, do not have a ballast, produce directional light and it is possible to produce light only from the most productive portions of the light spectrum.

Learn the Basics of LED Grow Lights

Learn the basics of LED grow lights, what they’re made of and how to decipher the specs on a light. There are 4 basic components that affect the performance and lifespan of an LED grow light.

  • Heat Dissipation – Heat dissipation is the most important factor in any LED light but is especially important in a modern LED grow light with higher wattage LEDs. Each LED in an LED grow light should have a sheet of aluminum with molded fins built in. This device is called a heat sink and will absorb heat created by each LED and dissipate that heat away from the LEDs. This process is vital and the quality of the heat sink will be a major factor in determining the lifespan of the LED grow light. Cheap LED grow lights are typically made with a flat sheet of aluminum and do not include fins. A poor heat sink will degrade the LEDs quicker an shorten the life of the LEDs. At ALL LED we use a molded aluminum heat sink with grooved fins for increased heat dissipation of our LED grow lights.
  • LED Quality – The quality of each LED and the company that makes them is a major factor for both longevity and performance of any LED grow light. The top companies that make LEDs are CREE, Bridgelux and Phillips just to name a few. If you buy an extremely cheap LED grow light you can almost guarantee your light is made from cheap Chinese LEDs that are simply made to save money, not perform. At ALL LED our LEDs are all made by the top companies in the world and have been tested by us both in our labs and in the field to give you the highest yield and last the longest. We also guarantee every LED in our lights to last at least 3 years or we will repair your light for free.
  • LED Wattage – LED grow lights can have LEDs with wattage ranging from .05w per LED to as much as 50w per LED. The wattage of LED your garden needs is based on the type of plants you are growing. If you are growing plants you intend to harvest and need the highest yield per watt possible then you would do best with our 3w Extreme Flower. Although you see many companies claiming that 1w per LED beats 3w per LED, this is just wrong. It’s not even fair to compare the two, 90 3w LEDs are much more intense than 90 1w LEDs. See this comparison of an all 3w UFO vs an all 1w UFO. 1w per LED can grow well but our field tests along and our lab tests prove that a 3w LED is the perfect balance of light intensity without creating heat issues like HID lights. and the budget you have for your gardens lights over the next 3 years. Why 3 years? Our lights are guaranteed to last 3 years without any failure, therefore you can based your budget over the next 3 years which you would be paying for new bulbs every 6-12 months and paying for increased electric costs

Why Buy or LED Lights

Why our products are top rated:It is important to emphasize that the key factor that makes LED grow lights so advantageous is the fact that all of the light that they emit is within the spectrum that is usable to plants. The whole purpose of the light is to catalyze the process of photosynthesis as it is absorbed into the chlorophyll molecules of the plant. Each color of light we offer is specifically design for growing plants at certain stages of growth or all stages of growth.

Why LED Tubes?

LED technology continues to develop rapidly as a general light source, and more LED light fixtures, for example T8 LED replacement lamps, have been introduced on the market. Recently, commercially available white LEDs luminous efficacy have achieved over 90 lm/w, compared with 80-100 lm/w of existing T8 fluorescent lamp. Existing T8 fluorescent lamps work with troffers, whose efficiency ranges from only 60% to 74%. In addition to having a high efficacy, LEDs also have a longer life time, they save energy and are mercury free.


It is not always practical to replace existing T8 fluorescent lamps with T8 LED replacement lamps. Not all T8 LED replacement lamps are good replacements for conventional T8’s. This fact sheet makes describes a detailed comparison on performance of T8’s. The focus lies on optical, electrical, thermal and reliability. The compared products are ALL LED T8 LED replacement lamps, Philips T8 fluorescent lamps and commercially available T8 LED replacement lamps from other suppliers.

Real Cost of LED Lighting

There are many reasons preventing customers switching to LED lights from conventional lighting. But none larger than the lack of awareness about this new technology and the multiple benefits that it has to offer. And even those few, who are aware of this new technology, are deferring the decision because of its higher initial purchase cost. An in-depth analysis into this technology reveals that it is economically, environmentally and technically feasible to invest in LED’s now. Analysis reveals that this high initial cost is recovered in many ways, once the investment is made.

The Truth About Wavelengths

Not all light is created equally. And neither are LED lights! At least not as far as plants are concerned. This is a brand new model which uses the most powerful LED available, 3watt chipset and a redesigned heat sink for reliability. Beware other companies selling inferior Chinese chipsets and not modifying the heat sinks. Multi-watt LED’s need special cooling; lighthouse disperses their LED’s and has added additional FINS and higher output fans to address this issue. Lighthouse light is unique and the only company to use 425nm blue LED’s for better flowering performance. Below is an accurate chart of light spectrum usage by plants.
