KosunRefill 16" F10T5/830/L Fluorescent Light Bulb Replacement for Jasco,Philips,Linear T5 10W 3000K Warm White Bulbs,G5 Miniature Bipin Base,(6 Pack)

I bought these to replace an 18 year-old Jasco F10T5/830 bulb that had been burned out for quite a while. They are a perfect match. The color is a warm white, which is what I was looking for, because the light fixture is under a cabinet over a desk in my kitchen and I didn't want something too glaring. It gives off plenty of light for that purpose and there is absolutely no flickering. It is nice to have a spare bulb, because I had a difficult time finding a match because my fixture was so old.

This is my 2nd order. I have several lights needing these. Fits perfectly. Works well. Last long.

My order arrived on time, as specified, and in good condition. Bulbs are as described.

Fast and accurate

Only one of three bulbs works as expected. Two of them flicker/fluctuate after being on for 10 minutes. Update: seller contacted me and replaced faulty bulbs.
