desertcart.com: Circle F8T5 Flourescent Light Bulbs - 12 inches Under Cabinet Bulb - Cool White 4100k 8 Watt Tube Bulb - Pack of 6 : Industrial & Scientific

Review: Fluorescent light bulbs - I have bought these fluorescent bulbs before and they work fabulous. I used to buy them from an rv parts department. And they closed down. So now I get em from desertcart, and they're even cheaper.Thank you
Review: 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.
