i bought a light set from qian hu a few months ago, the brand and model number as taken from their website is: "AL-147:Aqua Zonic Super Bright T5, 45cm - 2 x 16W"

the tubes that come with the light are 397mm 10000k, and i've been looking for 6500k tubes but i can't seem to find any that are of this length and wattage (16W)

397mm would be 1.3ft, has anyone ever come across any 397mm 6500k 16W tubes? do let me know where i can get them, thanks!
