300 Watt LED Grow Lights

A 300 Watt LED Grow Light is the perfect balance of power and efficiency. When switching from other lighting technologies, you will likely see huge improvements in your grow while shaving money off your energy bills.

Here at Hydrobuilder, we have a bunch of awesome 300 watt LEDs. If you're looking for the best one on the market, you cannot go wrong with the KIND K3 XL600 LED, or the Loriflux Full Spectrum LED. If you are looking for something a bit cheaper that will still deliver impressive results, check out the HLG ELITE ECO 360 Watt LED. Regardless of the type of light you're looking for, we have it here.

300 Watt LED Coverage Area

With a 300 Watt LED grow light, you can cover a small to medium-sized grow. The specific coverage area will vary by light to light, as each one is different in terms of uniformity, output, etc. But on average, you can expect to cover a veg area of 5' x 5', and a flower area of 4' x 4'.

How much electricity does a 300w LED light use?

These 300w LED's are crazy efficient, saving you big money on your energy bill when switching from older, outdated technologies. During veg when you run the light 18+ hours a day, you won't pay much more than $15 a month. This obviously depends on what you pay for electricity (KW/Hr), along with the efficiency of your specific LED. But it's a good estimation, and once you flip to flower, you'll pay even less!

These are just a few of the hundreds of LED grow lights we carry here at Hydrobuilder. We have LED's ranging from less than 100 watts up to 1,000 watts. Shop all of them to find your ideal LED!
