i have not found not even close that you save 20-30% useing digital.maybe 10%tops if that.just think how sweet it will be with a dual... only 1 ballast, 2 hoods, its digital so its 20-30%more efficient than a magnetic. thats what i would do if i was u for sure. i bet that it would be less if not the same amount of power used if your current 1000w ballast is a magnetic. plus it would look good . u would walk into your grow area and everything would look sweet. plus it would pay for itself in saved energy the ballast im talking about does not get hot either thats another thing to thhink about it will be easier to keep your area at the desired temps
i use the solarmax and the ceramalux,to be honest the 50 dollars extra you pay for the solarmax,i never could tell the differance from the ceramalux by phillips.i think the solarmax dims faster,just my 2 cents.but every one swares by the solarmax so i got some on sale.that makes me happy i cant wait to open my box with my 1000w light in it i havent even seen this thing on. i need a bulb people ? where should i get one? whats a good one?
ya ive seen them,never used it seems a little pricey,but ya the ceramalux will do fine,the solarmax never increased my yield but apparently the plants love it,i just wish they would show more appretiation for it and yield more.so go with the ceremalux? have you guys seen that bulb that is a 600hps and 400mh? are those good? it was 250 in the store that seems like alot!!!!
