Philips advance centium ballast last longer in commercial applications. you may also consider these https://www.1000bulbs.com/product/91989/PLUSRITE-7319.html.they have a good reputation in commercial applications and a higher ballast factor than fulham ballast. I use them myself 55 watt 2G11 CFLs in a 2ft by 2ft by 8ft closet and am very happy with them. fulham ballast have shown a higher premature failure rate in commercial buildings.I have used Philips ballast but find the plusrite ballast to to be a little more effiecient and very reliableAre philips ballast, better, then workhorse. Just rebuilt my t5 setup. As I bought parts when I had money. $80 on ballast, $ 15 on sockits, lights where free.
I think these bulbs like many aquarium plant growth bulbs are intended to be used with cool white (6500K) bulbs which would provide full spectrum coverage.when used in conjunction with cool white bulbs these "purple bulbs" show a little better performance in flowering than the conventional 6500K/3000K flowering mix.the improvement is very small and the par bulbs are much more expensiveCrap science to take advantage of those who drank the RB Kool-Aid
Plants need a full spectrum to express their full potential
Eliminating the non RB WILL cause MUTATIONS

my bulbs are 2 years old running 12/12 continuously and still going strong.my light meter shows the output is still over 90% of new bulbs. but I use commercial bulbs and not bulbs from the hydro or aquarium shops which may be low quality bulbs that are repackaged and sold for a premium price.high quality commercial grade bulbs are inexpensive ad can last 20,000 hoursI made a post a while back saying that t5s last for 20,000 hours and was corrected. I now see for myself that two of my eight bulbs burnt out after six months. however this was after 2 weeks of a fan being pointed at them. never point a fan at the t5s they will burn out. I corrected the problem and no more have gone out so far
I personally woukd have started the plants under the 4ft t5 light. Get them under the veg light as soon as the have a good tap root and 2nd set of leafs.Hello everyone. I have 2 bubblicious from nirvana seeds. I started them in 1 gallon pots. I have them under a 26 w 6500k bulb each. They will be 2 weeks old tomorrow. So how do they look for 2 weeks old? And should I put them under my 2ft x 4bulb T5 light now or wait alittle longer? How close should the T5 light be from the plants? any help would be great. Happy Holidays.View attachment 3570190 View attachment 3570191 View attachment 3570192 View attachment 3570193

This will be a fun thread.Currently stuck with T8's. Cant find the ballast at homedepot or lowes yet. Its like nowhere seels em but online and for 150the a piece, i could get a 400piece watt hps online for that price
