600 Watt Lamps

600 watt grow light bulbs are the most popular bulb and have been for many years now and are the best selling bulb on the hydroponic market, they have produced many thousands of plants over the years, proving to be a great choice for growers.

The 600 watt grow light bulb is superior to the 250 watt and the 400 watt grow light bulb down to the higher power out put of the 600 watt grow light bulb - leading to bigger yields that they can produce. In figures the 600 watt grow light bulb is actually superior to the 1000 watt grow light bulb too, due to the large heat output that the 1000 watt grow light bulb produces which is a down side to the 1000 watt grow light bulb within an indoor grow room. The 600 watt grow light bulb produces a great output of plant usable light with as little heat as possible from a grow light bulb. So if you are looking for a standard grow light bulb that will if used correctly produce great results then the 600 watt grow light bulb is a great choice.
