The clamp is designed to keep the grow light steady when it's standing up and its arms are positioned accordingly. Without utilizing the clamp, the grow light may not be able to hold itself steady. The picture shown on the page, which suggests otherwise, is for reference and product photography purposes only.

The Saber DUO only produces red and blue light. It does not produce ultraviolet light.

The clamp will clip on objects up to 2.5 inches.

We recommend that the plants be kept at least 20 to 30 inches away from the grow light.

Lumens measure how bright a light appears to the human eye. White and yellow lights will appear brighter as compared to blue and red lights. A high lumen value does not necessary mean that the light has the optimum color spectrum for growing plants. Thus we do not provide this metric on our grow lights. What is important to look out for is the color spectrum of the grow lights.

It is actually normal for the lamp to generate heat, particularly the tubes which are lit. The summer season, along with outdoor and indoor temperatures, is also expected to contribute to the heat. This is nothing unusual, and under no circumstances will this affect the lifespan of your LED Lamp. Like any other lights in the household, the lamp will be hot, but its clamp and ‘gooseneck’ shouldn’t be as hot as the lighted tubes. Rest assured that the lamp you received has undergone and passed all the necessary tests to ensure your safety.

LED are more efficient than any other type of lighting, which basically means you pay less in power costs to get the same results. Running the Saber DUO for 12 hours a day every day, will cost you approximately $5 per year or about $0.40 per month.
