I need to replace a 30" bulb in a t-5 HO light, I believe they are 31w a piece.. as can anyone recomend a nice brand to buy with a good output, I do not have a light meter and do not have any easy way to get my hands on one, so you gurus out there that have tested them, which one will give me a nice high output over other brands??

where to buy also if you happen to know

thanks a ton

Mike
