Thu Feb 19 23:36:12 PST 2015
there is a transformer & there are 8 X 4 ft light strips w/10 leds/4ft
strip. label say:Trintiy Mfg LLC P/N 401415 24vdc/.55a(13.3w) 6000k 2B-R2.
i tied 4 strips together onto a 1x2 board to form the relative dimensions
of the flouries & was told "it's bright", "it's a different kinda light",
"it's about 1/3 as bright" & "it's about 1/2"
