Two 7.5 watt LEDs will not provide more light than one 58-watt Linear
fluorescent lamp - not even close.  You need to read real data sheetsm
and not just marketing hype.

15W LED v. 58W flourescent, not a hope.

Depends entirely where you NEED the light. The LED can provide as much
light in a restricted area as the flourescent does - but will NOT
light as large an area to that brightness. So the question is - how
much light do you need and where???
If the light scattered all over by the flourescent is needed - use
flourescent. If it is just wasted (not needed anyway) try the LED
solution.

How does distribution affect light colour?
