The beauty of systems like MH is that being spot lights they have certain benefits over tubes.

Firstly, they do not light the entire aquarium uniformly, thus giving the fish some shaded areas to retreat to if they are feeling a little nervous; relaxed fish are happy colourful fish.

Also, seeing fish swimming in and out of pools of light is also very pretty and looks like beams of sunlight penetrating the water and projecting shadows on the substrate below in a very natural manner. Of course light does scatter when it hits the bottom of the aquarium so it’s not like everything outside of the shafts of light is pitch black.

Unfortunately, as you say MH produce a lot of heat. They also only come in very high powers. There is an alternative which I have tried before called Solux.

Solux are low power halogen lights (35 -50 watts) but unlike normal halogens these have a very high CRI (colour rendering index) The company claim it is 98 which is frankly a little hard to believe. They emit almost no light in the infra red or ultra violet which adds to their effectiveness in an aquarium environment and they run cool to the touch.

I haven’t used them in a 2 foot deep water column but they are quite cheap so you could give it a try and see how it looks in your tank.

This is a link to a UK site which sells them. You'd best source them yourselves in your own country where it will no doubt be cheaper but this site provides an illustration of the operation of Solux:

Thanks for the pointers but don't think Solux is available here. I like MH but I can't use it as the main lighting system because the aro is a surface swimmer. Too glaring plus the heat might force it to seek refuge somewhere. I feel T5 is a good compromise.

When I first ordered solux bulbs I shipped from the US. Being MR16’s they’re quite robust and unless someone jumps on them they should be ok.

The last time I shipped something from Singapore (or at least that region) it was when I bought a copy of Awakening the Dragon. It only took a couple of weeks to arrive.

The only problem with shipping the bulbs internationally is that you will be paying UK or US prices. This would work out at 24 SG$ per bulb which would last approximately a year.

Thanks. Must consider How am I going to incorporate into my existing hood. Have you taken any pictures on your fishes using the solux? If so, can post some?

My mistake. That janet from aquamarin reminded me about 80W for 5'. She didn't tell me she has solite HO T5 set! Only saw ATI. 1 set 5' with 2 T5 is one OR6500. 1 set with 4 T5 equals to 2 OR6500! With that amount of money, I can cover the whole tank top with solux as recommended by Aropal and including some spare bulbs.

Slave flash???? Don't think so. Current camera no hot shoe somemore!
