UFO550 New Tank Lighting Needed?

Hi

Just starting a new thread regarding another post I made to ensure the subject is accurate.

My tank is a UFO550 and only seems to have 11w bulbs. Im getting issues with the plant leaf edges turning black then going translucent and after researching feel it may be a lack of light. The tank is 100l woth 78l volume.

Has anyone upgraded the light in this tank?

Just read that 9w fluorescent is equivalent to 40 watt incandescent so maybe this is why the wattage appears low when in fact its about right as 40w is equivalent to 2.35w per gallon
