Is T-12 floro's -- a bad word??

[Tripco]

Osram T8 lumilux are very good choice for fluo grow. They have more lumens than basic models. Basic 36W (1200mm) Cool White has 2850 lumens and Lumilux CW has 3350lm. But Lumilux models are 2x more expensive than basic ones.
Sylvania, General Electric and Philips have similar models.
