i take it its being used in the states with a voltage rating of 125v?
i got a timer from a grow shop for £5 ($10-12)to run with my 250 watt MH and it works a treat
some of the more expensive shit may last a bit longer but will cause much confusion and could blow your ballast as soon as you switch it on,did you buy the timer from a grow shop?if so phone them up and ask about it,they are there to help
wardrobe grower 78 Reviewed by wardrobe grower 78 on . Question about timers Anything specific to use? I have a timer I bought to run my light, its a "heavy duty" timer, rated I think up to 1750watts, this for a 400 watt light. I plugged it in, but I wasnt sure if the ballast was charging up (which is doesnt really do) or if it was going to fry the hell out of it. Its made by Intermatic, it has a ground, Indoor use only, (growing indoor) It says 15 (A) 1750W "T" "H" "TV-5" "12 FLA (72 LRA) Motor, 125V A.C. 60Hz Hope someone can help... Rating: 5
