Generally, the best cheap grow light should have a dimmable function with a knob. It should also be easy to adjust its brightness level and hanging height.
Lifespan: How long should a grow light last?
LED grow lights have a longer lifespan than other grow lights, including HID. Some units have a lifespan of only 50,000 hours which is excellent considering their low price. However, other lights have a lifespan of 100,000 hours, making them highly durable.
Cooling Features: What colling feature fits most for growing light?
Like other lights, LED grow lights also produce heat. Therefore, you should get a unit with aluminum heat sinks to help dissipate the heat. Such units boast a fanless design for quiet operation.
Alternatively, you could get a light with integrated cooling fans. However, with this option, you may not enjoy silent operation.
Light Spectrum: Which should be chosen?
Some lights will only replicate a few color frequencies, including red, white, blue, and IR.
Meanwhile, some units can replicate more colors like orange, yellow, and UV. For best yields, we suggest choosing one with more color frequencies.
Power Consumption: What should be the maximum power consumption for 4×4 grow lights?
Your LED grow lights must stay on for 16 to 18 hours daily. This may lead to increased power bills. Therefore, the best unit should consume only a little electricity.
Fortunately, all our recommendations use less than 500 watts of power. But of course, the lower the wattage, the better.
Ease of Setup: What determines the ease of setup?
Generally, LED grow lamps are easy to set up. However, it would help to get a unit that comes with a clear installation manual, a hanging kit, and rope hangers. These will make the setup easy and quick. And if you want to link more lights, get a grow lamp with a daisy chain.
