Many of you may be aware that my favourite T8 tube for the planted tank is the Interpet Daylight Plus. It gives excellent colour rendition and plant growth and I've recommend this tube time and again to fellow hobbyists through various forums and PFK.
However, Interpet have replaced their excellent Daylight Plus T8 tubes with Daylight Marine (10000K).
It also has an internal reflector. Half of the inside of the tube is coated with reflective material so in theory you don't need a seperate reflector.
Trouble is, for some light units i.e. Juwel light-bar and Hagen units, the alignment of the reflector is 90 degrees out i.e. the reflected light points directly toward the front or rear of the tank, depending on how you install it.
I have tried out the new Daylight Marine and the output is a crisp white, but not the nice green rendition of the original Daylight Plus. I also needed to use a reflector to bounce the light downwards from the 90 degree-out light direction....
I have e-mailed Interpet direct about this, and the lack of PC T5 reflectors. I will let you know if they respond.
Meanwhile I will be looking in my LFS for some old stock of Daylight Plus.
Perhaps you may prefer the new 10000K Marine tubes, but I know I do not.
Just a heads up.
