A7 Answer: Many LED grow light companies overstate the wattage their lights actually run at, instead using the theoretical limit of the LEDs in the light. If this much energy were run through the light it would likely cause permanent damage to the light and shorten the lifetime of the LEDs. Some other manufacturers will misleadingly name their LED grow lights with the wattage they claim it will replace, such as a 1000 watt HPS.
When buying LED grow lights you should always make sure the company is claiming the actual wattage the grow light will use in your garden. You are essentially paying mostly for wattage when you buy LED grow lights so if you are misled in the wattage you are not getting what you are paying for.
