600 watts 😮‍💨. Friday, I achieved a victory I have wanted for awhile. Pulled 600 watts briefly on the rower during the second AO we had. Not sure I’ll ever get more than that but it feels good to say I got it to 600 as a 5’4” female! Two years ago when I started OTF I hated the rower. Now I love it! Realizing it’s a power clean 600 watt hps are the most efficient of all the bulbs, giving more lumens per watt than any other bulb, but not by a lot. If 600 is enough light for you then stick with the 600. Also, a ballast will use up 20-50 watts on top of the rating on the bulb. So a 600 watt will use about 630 watts, but two 400 watters will use about 860. ive used a 400 watt with little cheap 45 doller hood w/ no glass sheild. it produced a lot of heat. im now using a 600 watt with air cool hood with no inline fan. it has a glass sheild. the 600 is a little less hot then the 400 without the glass. my homie has a 400 watt with a 4 inch inline fan with aircooled hood and it isnt hot at all. With a 600 watt dimmer running a full 600 watts of lights, the temperature got up to 135 degrees. At 750 watts, the dimmer switch got up to 158 degrees. Next, I tested a 1000 watt dimmer with a Cali is very expensive, where i live in the Midwest is cheap. Leds are most generally much smaller then their advertised wattage. A 600 is probably actually 300 watts or less. All the 600 will mean is how many watts the diodes can handle but they're ran at less so the light lasts longer. It is not an equvelancy factor. 1 of leds dirty little Keep using your 600w HPS for flower. LED is not going to produce a superior result, and you'll spend a fairly large chunk of money on a quality board capable of flowering in a manner equivalent to the performance of a 600w hps. There is nothing wrong with your 600w hps for flower and there's no need to replace great equipment. While a watt is a measure of power, a kWh is a measure of energy. Energy is defined as the capacity to do work, such as creating heat, light, or motion. If you run a 60-watt lightbulb for one hour, you've used 60 watt-hours, or 0.06 kilowatt-hours, since a kWh is 1,000 watt-hours. In other words, 0.06 kWh is the amount of energy you need to run 70OBHs.

is 600 watts a lot
