WRONG! T-5's do not last 12 months, their spectrum goes out in about 6 months making the cost more. secondly, regardless of the maturity of the technology, t-5's are not better than pc's. the scotopic lumens makes it appear brighter, but in effectiveness, pc's are better. dispute it all you want, t-5's lose their spectrum in 6 months. feel free to post sarcastically and put up numbers supported by your own preconceived notions of it t-5 being better. it doesn't make it so, t-5's are , ahmmm , a sham
