"I had a hard time finding a replacement 8 watt T-4 (3000K-warm white) fluorescent bulb. Savio Lighting d/b/a Slim Fluorescent had a full selection of T-4 bulbs in stock. I placed an online order and received confirming emails with tracking numbers that the 2 bulbs shipped out the same day. Upon receipt the bulbs appeared in good condition but I found that one of them was defective. After a quick call to their customer service, a replacement bulb was on the way with no hassles.

Based on my experience, I would recommend Savio Lighting. "
