Combination lighting

[Carpman]

Hi all as I know very little about lighting I thought I would put this out there for those that do know! I have a standard juwel t5no system which gives me low light, can I replace 1 of the bulbs with 54w t5ho to give me medium lighting setup?

Generally all the Juwel T5 light units are in the high light category. See chart below.

You don't state your Juwel tank, but generally they are about 20" deep which puts a single T5 tube as medium light (60-70 PAR) and twin T5 as high light (120 odd PAR). Of course adding reflectors makes that even more.

Hi Ian my tank is juwel 190 trigon currently running 2 x 28w I thought these were classed as t5no"s

I thought all Juwel T5 tubes are HO versions. ? (I may be wrong). Anyway if not NO's are only about 1/3-1/2 dimmer than HO's, thus with reflectors will be 120-160 PAR, which is still high light.

Dont quote me on this as I may be wrong but I think the HO versions are the 54w bulbs.
So my standard bulbs without reflectors would be equivalant to medium lighting ?
