4X8w converted bulkhead - Lit end view

The ends and the bottom of this bulkhead are the only areas that seem to have anything that looks anything like refractors. The tube set lowest into the diffuser is a bit lower than I'd have liked it to be, but the refractors work extremely well to spread the light from it, so its something I feel can be overlooked. Surprisingly, barely a shadow is cast on the ends from the brackets, another sign of just how well this bulkheads took the conversion.
