This entry is part 6 of 5 in the series LED Grow Lights Series
Coverage Calculations: To figure how many lights you need for your space, take the coverage area of the light you are looking at and divide your space into sections of this size. Remember, low wattage LEDs must be placed very close to plants due to low intensity and therefore the coverage area is reduced. We recommend all 3w LEDs to allow for a broader more intense coverage area. Caution: The coverage area shown for many LED grow lights is grossly misrepresented. If you are growing baby spinach you could probably get away with the extremely high coverage areas some companies show. See Comparisons and Claims below.
LED Grow Light Success Formula: Success = High Light Intensity + Lowest Heat + Lowest Power Consumption There are very few companies that can achieve this formula, see the links below for our choice on LED grow lights. You need to make sure your LED grow light will provide High Light Intensity but also keep the power consumption to a minimum and thus keep the heat down. The more wattage you run through each LED the more heat you produce and the higher your electric bills run. The entire point of LED grow lights is to minimize the power bill and eliminate heat issues. Some companies would tell you they have the most powerful LEDs but don't tell you how this impacts your heat and your electric meter. Remember: You need High Light Intensity with the Lowest Power Input. Electricity creates light and heat therefore the light should use the least amount of power to reach High Light Intensity. Caution: Excessive electrical input causes drastic heat increases and reduces the life of the LEDs.
Guarantees are only as good as the company offering them. With that said, some of the worst companies to buy grow lights from(or any product) do not offer any guarantee. Always look for at least a 90 day guarantee and a 3 year warranty with the shipping paid by the seller. The LED grow lights we recommend below come with a 90 day money back guarantee and a great 3 year warranty.
Buyer Beware! If it sounds too good to be true, IT IS. Some LED grow light companies make wild claims and lie about their lights. Common false claims to look for: 1. Growth of LED grow lights compared to HID lights. 2. Quality of the lights. Look at the guarantee since most quality LED grow lights are offered with at least a 90 day guarantee. 3. Lifetime of the LEDs. The quality of the heat sinks and the lights design will determine how long the light will perform. Cheap LED grow lights and lights that input too much power per LED with fail quickly due to heat issues. Cheap LED grow lights are not really worth anything when they fail prematurely. 4. Bait and Switch. Watch for companies that show certain lights over plants but then ship you a lower quality light. This is illegal and considered "bait and switch". Look at the vents in the side of the light shown in the picture, then look at the vents in your light when it arrives, they should be the same.
The company you choose to do business with is very important. If they are a scam then the guarantee and the warranty they offer is worthless. Research the company's background and call them with any concerns or questions you have. Look for the following information to be clearly posted and easily accessible to visitors. Company name. Company address. Terms and Conditions. IMPORTANT - Read their fine print. Better Business Bureau Listing.
LED Grow Lights are commonly named something like "AB400" but this is completely useless in determining the power and intensity of the light. Some LED grow light companies will put a number in their lights name that is much higher than the actual wattage of the light. For example a light called "AB400" may only use 200 watts of power but you may buy it thinking you have a 400w LED grow light. Dont be fooled, ask the actual wattage of the light if its not listed. Remember though, too much power per LED is unsafe and will result in a shorter life for the LEDs causing failure prematurely. The lights we recommend use all 3w LEDs but a low current that results in high light intensity and long life.
