My light has been on for 2 weeks on 18-6 with no problems. Yesterday the power went out 3 times reasons unknown. It went out for a couple minutes, then came back on & I turned the 400w off & all the BR lights were dimmer & everything else I used ran at half power. Then it went out again 20 minutes later & came back on everything was fine. Then my light came on this morning and was on for an hour then it went out again. Now it is on for 2 hours no probs yet. Any ideas, is light shorting out elec.? Bad connection somewhere? Feel free to comment

Just the lighting for your grow? Or, your entire house? What are you using exactly in terms of lighting?

i have a 400 w mh hooked to timer on power strip. lighting to the whole house went out so when it came back on i turned the mh off and checked my other lights and they were all dim so i plugged a fan up and it only ran half power they went back off and then they worked fine. its been on for about 7 hours and hasnt shut back off yet. i dont know. I was thinking about using one of those 105 watt cfl instead of HID any ideas? And also this one has 40,000 lumens 3000 kelvin is that good for flowering?
