Hi all, QUOTE="Marc Jackson, post: 558210, member: 18230"]I was hoping to have the likes of Dennerle, JBL, Arcadia, Interpet, Hagen.[/QUOTE]It doesn't make any difference what the brand is, there aren't any "special phosphors" etc. there are just specialist "aquarium" tube sellers that are economical with the truth, and extravagant with your money.

Have a look at <"James' Planted Tank: T5 lighting">.

cheers Darrel

They keep growing plants like a champion for the last 10 years for less than £3 a bulb:D
It is really funny how my LFS charge £15+ for the branded ones

Where can I buy 6500k T5 HO 80 watt tubes?
Toolstation & Screwfix do 'warm' and 'cool' tubes. Or go online and look for lighting wholesalers. They will do a range of tubes and will give temperature and colour rendering (CR). The closer to 100 the CR value the closer to natural light. For a planted tank I used a mix of cool white and grow-lux with good results. Now gone over to ANO's LED's but again with a mix of colours including grow-lux types and bright full spectrum whites. Note a high CR as in a North Light will look pale and cold to the eye. Humans see better under a more yellow light, hence 'comfort' lighting which can have a high efficacy rating ie just looks bright.

Energy outputs for most T5's are much of a muchness. They just look different brightness's and colours to the eye. Also think about the plants spectral needs.

Tubes from LFS are over priced. Most, if not all, modern tubes, are Triphosphors so why pay for a fancy package. Look at the spectrum output or ask for it for the tubes you are thinking of getting. Triphosphors can have band gaps in their spectral output hence a mix of tubes can 'fill in the gaps'.
