Frequently Asked Questions

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 Lance DUO only produces 3000K warm white light. It does not produce ultraviolet light.

The clamp will clip on surfaces up to 2.5 inches.

We recommend that the plants be kept at least 8 to 12 inches away from the grow light. We have designed the light so that you can conveniently modify the distance by adjusting the gooseneck arms to your liking.

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.

No. This model features a built-in timer that can automatically turn on and off for your convenience.

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 Lance DUO for 12 hours a day every day, will cost you approximately $4.80 per year or about $0.40 per month.

Grow lights

Easy to use and set up! Needs to be pretty close to the plants to get the full spectrum


Not enough light for seedlings

I got this light to use for starting my vegetable seeds indoors. I put it the recommended 12 inches away and once sprouted the seedlings started getting really leggy(reaching for the light.) I have moved it closer and closer to the seedlings and they are still leggy. At this point it’s nearly touching them and hasn’t burned them at all but they also don’t seem to be getting enough light. I’ve moved them to the windowsill with the light so hopefully the combination of both will do the trick. I don’t like that they don’t give you exact light measurements of what this puts out in lumens but I suspect it’s low. I used a light meter and measured the light in footcandles and the reading was only 25. That’s really low! I wouldn’t recommend this light and will probably end up returning it. May work better with plants that only require low light though or supplementing the natural sunlight.

Lance Duo Review

I bought two of these grow lights for the darker parts of our home and our plants are ecstatic!

Love my grow lamp

Great experience


Works great

I love the lights, lots of options for brightness and 3 options for the timer. I gave it a 4-star because the clip is very difficult to open.
