So how close are the 5000k LED tubes to true D50? I couldn't find any except on alibaba that advertise a D50 output. The ones in our office, which is a big light box essentially are fluoro T8 and cost about 137 per fixture. Are there any Energy Star qualified tubes that are "close enough" for the shop floor?
