For example their CRI may be 530. that would mean that their accuracy is between 50 and 59% accurate to the colour they are supposed to give which is represented by the 30 which means 3000K
Therefore a 100% accurate lamp would give a perfect 3000K. The further away from 100% you get then the further away the difference may be.
No idea of how much but a 100% will be 3000K. An 80% may be 2500 - 3500K. A 50% may be 1500 - 4500K!!! These are just examples and not factual as like I said I don't know how far the accuracy goes.
What it means is that you may like the 'hue' a 4500K gives (on the whiter side of pink). a 100% will give you this colour a 50% could be out as far as giving a yellow 'hue' (on the low error side) or a green 'hue' (on the higher error side) big difference!!!
The Aquarium tubes in the main are 70 - 90%. There are T8 tubes on the market (still cheaper than aquarium tubes and available on lampspecs) that are 98% accurate
I would suggest only buying tubes that are 80% (CRI beginning with 8) or higher unless you are not bothered about the colour your tank looks like

You seemed to have gleaned quite a bit of info from what little was available from the link I posted. Some of it went woosh as it passed over my head.
I couldn't see that they were rated as 30 or 3000k.
Which are the 98% tubes you mentioned on lamp specs? I've seen the triphosphor and the grolux ones.

/www.lampspecs.co.uk/Light-Bulbs-Tub...aphica-Pro-90_2Cheers.
Sadly they're 48" (or at least it says 4'), so they wont fit under the hood.
I was asking earlier if the triphosphor tubes were ok in fish tanks, so that's good to know. I've used them before as lighting for a studio and found they do give much more of a white light compared to the standard tubes, which I always find a bit yellow.
Looks like these might be my best bet?

The first ones you linked to are actually 3500K - yellow to pink but only 54% accuracy may mean they are way off that colour.
The latest ones are 4000K and therefore VERY pink (if that's your thing) however being 80% they will be pretty close to the 4000K that they say they are.
The studio ones I linked to will be a 6500K or thereabouts and that is why they are white. Standard shop lights and household lights as sold in B&Q (including the CF energy saving bulbs you put in your ceiling lights) etc are usually 2700K ish and therefore a yellowy light.

Some pink things I like, but that's another story.
Definitely don't like the tank lights with a red hue, had them before, same with yellow. Much prefer the lights that show the natural colours. So it looks like I'm out of luck with cheap T8s at lamp specs.
