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 Reflector-Series 300W VS MARS HYDRO ECO 49 300W

When two lights have similar features like the VIPARSPECTRA 300W Grow Light and the Mars Hydro Eco 49 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.
