Diy Lighting On Bowed Acrylic Tank?

[Mike_SE]

i have got a bargain 150 litre bowed front tank. but it is just the tank, so naturally i need to add some lighting. ive got the right sized tubes and a power unit, but i am after ideas how best to fix this to the lid? does anyone have any similar setups?

all help appreciated
