so I've got an odyssey 4x t5. 2x 10k & actinic . Not the best , but at r1000, a bargain. 3 ft on 4 ft tank. Bought a strip light for R150 and installed it inside odyssea for moonlight. Then came across LED spotlights. So put 2 X 10w led (R125each) in for a bit of extra lighting. Can it do any harm, should I add another 2 X ? Or maybe upgrade to 2 X 20w ? In October I am going to USA ,( plan on picking up something there ) so just looking for a cheap upgrade to current setup till October . Any advice greatly appreciated.
