Best In Class Bulbs
I've been using F8T5 bulbs as TV backlights in my living room and bedroom for 20 years and have never seen bulbs that last as long as these. I was going to replace both fixtures with LEDs, but now I see no point. This brand is an outstanding performer.

Great price for lights bulbs hard to find in a store

8W warm white 29-530
Whilst i cannot rate the life span of a brand new tube, these lamps worked well straightaway, are brighter than those they replaced and seem reasonable in quality. For anyone needing specifics these are a direct replacement for hard-to-find warm white 29-530 (not 830) and will match surrounding traditional warm white tubes. Ordering from England, I have to say how reasonable shipping costs were for these lamps.

Great value
The price is great for these bulbs, the lifespan is definitely shorter than the more expensive ones.

Poor quality - die quickly
I bought these a year ago. Several have burned out already and of the ones that I just put in one had burned out and another is flickering. Very poor quality.A 30 day return window isn't enough for light bulbs. They should't die this quickly.
