Sunlight is electromagnetic radiation, which includes the visible light spectrum, infrared and ultraviolet light. Ultraviolet (UV) light has a shorter wavelength of less than 400nm compared to visible light. The surface of a plant has photoreceptors that can feel the quantity and quality of light they are being exposed to. When the hotoreceptors sense the […]

Why did NASA use LED grow lights to grow food in space? For the same reason that Indoor Growers use hydroponic LED grow lights to grow on Earth – because of the numerous advantages of LED grow lights over traditional systems such as metal halide, high pressure sodium and T5 bulbs. LED grow lights use […]
LED options for designer lamps Every designer knows that a good table lamp must not only be appealing to look at but must also be able to serve its purpose well. Thus, design aside, properly choosing the appropriate light source for a lamp should be on top of the designer’s to-do list. Power efficiency and cost saving […]
LED lights can be made using different sized diode chips from less than 1 watt per diode up to 20 watts or more per diode chip. The ideal chip size for a LED light will depend on the use for the light. As the chip size gets larger, the light is more intense but the diodes give […]
In a quest to find the best LED grow lights, I came across the question of which is better, 1w vs. 3w vs 5w diodes. I first started researching the history of LED grow lights and then compared different models of lights with varying diode sizes. My research led me to the following analysis. LED […]
What is the Optimal Diode Wavelength ratio for indoor hydroponic LED grow lights? It really depends on what you are trying to achieve with a given LED light. The optimal ratio will be different for a LED only for vegetative growth from a LED for flowering from a LED for both vegetative growth AND flowering. So how […]
How many bands of light are best for LED indoor grow lights? There are grow lights that are 5-band, 7-band, 8-band, 10-band, 12-band, 15-band, etc…Which one is the best for indoor medical growing? The quick answer is 6-8 bands of wavelengths. Anything more than six and you are missing essential wavelengths necessary for efficient photosynthesis. […]
Protect Your LED Grow Light and your Plants with a Power Stabilizer Buying a LED grow light is a capital investment for your indoor growing hobby or business. The investment offsets other capital expenditures by eliminating the need for ballasts, reflectors, heat venting systems and airconditioning in addition to lowering operational costs by dramatically decreasing the […]
