My tank currently has an "AquaWhite" T5HO tube and an "AquaRed" T5HO tube, which give a very white light, and a pinkish light respectively. However as the tubes came with the tank and have now 'aged' I can't tell the manufacturer.
I've looked on Lampspecs and intend to get an Osram Lumilux 880, and an 840 to decide which I prefer, and pair one of them with a Grolux tube for the pinkish light (Grolux on LampSpecs).
What I am not sure about though is whether these tubes are HO? I think the white ones are HO, but I'm not sure about the GRolux. If it is not is there a HO version that would be recommended for a similar colour output.
Thanks
