The manufacturer informs:

 Attention: the purchase of T5 bulbs must consist of multiples of 10 per wattage. Colours can be assorted according to requirementsas long as the total number of bulbs of the same length is a multiple of 10. (e.g. 5 Aquablue Special 24W + 3 Blue Plus 24W + 1 Coral Plus 24W + 1 Actinic 24W).

This neon is to be considered a complete tube, with an increased output on blue at maximum PAR power. This increased blue component helps to improve the colour rendering of corals with fluorescent pigments. In addition, this will lead to more light radiation useful for photosynthesis (PUR). 

Despite the high blue component, there is also a peak of emission on the red side, which will lead to an excellent enhancement of certain colours.

Coral plus is the latest development in ATI research with an output that lies between that of the Aquablue special and the Blue plus.
