your just over volting it for the wattage. be careful
stangle12 Reviewed by stangle12 on . ballast question hi people just a question about lighting ive got my floros in my veg box and ive aqiured a 250w ballast so i wired a 75w sodium bulb to it instead of a 250w because i just wanted to give my little seedlings a little boost until i put them under my 400w to veg (cant do this until i chop my other plant down) so as i was saying this 75w sodium it comes on and it goes bright as hell then it flickers abit and goese even brighter it does this for about 10 mins then it cuts out i thought it had blown Rating: 5
