While LED grow lights have changed the way indoor growers grow plants and simplified life to a great extent, they aren’t the same. This is why we always recommend looking at the specifications before buying a light. Today, we review 6 lights by giants in the LED grow light industry: VIPARSPECTRA and Mars Hydro. These lights range in wattage and are ideal for different growing needs. Follow our recommendations and you won’t experience buyer’s remorse.

Pro Tip: if you want your plants to produce high yields, pair one of the lights we’ve recommended with an awesome grow tent.

VIPARSPECTRA P1000 Full Spectrum LED Grow Light for Indoor Plants VS MARS HYDRO TS 1000W

When two lights have similar features like the VIPARSPECTRA P1000 Grow Light and the MARS HYDRO TS 1000W  light, it can be hard to pick the best. But since we must choose a winner, we have to say we love the VIPARSPECTRA light. Why? It has a better coverage (2’ x 2’ at 24”) and a much lower cost per watt ($0.57). Yes, it has a higher power draw, but it replaces a 250W HID/HPS system, unlike the Mars Hydro light which substitutes a 150W HID/HPS system.

VIPARSPECTRA Reflector-Series 900W  VS  Marshydro Reflector 960W

The last lights we’re pitting against each other don’t discharge the same number of watts, but they both come with a lengthy warranty. But this time around, our favorite is the Mars Hydro light because it can illuminate a 4’ x 4′ grow tent at 18″. While it has a higher price per watt than its counterpart, it uses 192 intense 5W Epistar LEDs while the VIPARSPECTRA light uses 180 5W LEDS.
