Glo T5 Overhead Lighting Unit

[aaronnorth]

How is the light spread on these? I am thinking about getting one (2 x 54w T5 version) but the 2 tubes seem too be close together and it looks as though the majority of the light will be focused just below the unit - is this the case?

also, what is the maximum width of the glass that can be used?

Thanks.

i own 2 of them (2x24w & 2x54w) and even though ive only used the 24 so far,(the 54 is waiting for me to setup my marine tank) i am very pleased with it. It's got a very good reflector in it. my tanks are only 12" front to back so i couldnt tell you how the spread really is but it certainly seems great to me although i havent used any other HO hoods before. HTH a little

Thanks for replying, the tank it will be going on is 16"/ 40cm

IMO that light will be plenty just place it as much in the middle as possible

Thanks for your help

Do you know what the maximum thickness of the glass can be?

what do you mean? the glass canopy?

Hi
I have the twin 55watt T5 on a 5x2x2 its spread seems vert good and the plant grwth has been beyond my expectations
i have it positioned slightly off centre towards the front - as it casts less shadows from the wood, but that is asthetics rather than need!
but all in all, a very good lighting unit, well worth the money.
My cover glass is 5mm if this helps?!?
Hope this helps
T.

Thankyou drtim.

i mean the tank's glass thickness where the legs attach (5mm glass, 8mm glass etc), because obviously if i have extremely thick glass the legs may not fit over the rim - hope this diagram helps to explain! The red is where the legs attach to the tank.

The reason i ask is because i will be getting a fluval roma 240 and i need to upgrade the lighting, but the rim is glued on so the thickness may be something like 20mm and i am unsure if it will fit - i know with the arcadia luminiares you can buy an attachment which allows you to use it on thicker glass.

Here is a picture of my current fluval, and as you can see it is really thick edge:

HTH, Aaron.
