Rena 4ft Lighting Upgrade

[jkc]

A couple of months ago I purchased the Rena Calvados Classic 120x50 tank. The standard lighting is 4 30W tubes. These are excelent tanks for working with. I love the way the lids come off in three sections however I cant see how I can upgrade the lighting without it costing an absurlute arm & Leg i.e over tank luminnaire etc.

This is a planted tank and I am injecting CO2, I would love to have that extra lighting under the hood as its so deep!!

Any suggestions on how to accomplish this??

Kind Regards

James
