Do you have an 8ft LED grow tube for growing romaine?

I'm looking for an 8ft, and a 6ft LED grow tube ideal for growing romaine, spring mix, and other quick growing items. We need 48-8ft bulbs, and 12-6ft.

Unfortunately, we do not have any 8-ft or 6-ft bulbs. One recommendation, however, would be our T5 linear fixtures which are modular and can be combined to create various lengths. 

Since they are offered in 2-ft and 4-ft variants, both the 8-ft and 6-ft lengths can be created with the various length combinations.

Below is the link to our "artist" series, for which we will be launching a comparable version for horticulture but in the same dimensions and form factor:
