Led To Suppliment To 2 X T5's On 4Ft Tank ?

[clivealive]

hi,
I have a 4 ft tank with 2 x t5's and feel it could do with a little more light.
The T5's are at front and back
was thinking of placing a led across the middle on or slightly above the glass cover but below lid
will this affect leds being just on or above glass
so it might only be around 3 -  3 1/2 ft ish overall.
i wanna spend under £100

what are my options?

??

thanks

What's the wattage of the lights you have and their intensity in K? You could save money by jut switching your lightbulbs.
