KOR 13W CFL Light Bulb, Double Tube, G24Q-1 4-Pin Base, 4100K Cool White – Pack of 4 (Replaces Sylvania, Philips, GE Models)

Our home office fixture uses these specific 4-pin G24Q-1 base bulbs, and finding a good value on them can be a challenge. I decided to try the KOR CFL bulbs, and they have proven to be an outstanding purchase. The pack of four was a great value compared to what I'd find at a local hardware store. The bulbs arrived well-packaged and in perfect condition. I immediately installed one, and it was a perfect fit, clicking right into the ballast. The light they produce is a clean, bright white at 5000K, which is exactly what I was looking for. It has made the workspace feel much more vibrant and has significantly improved visibility for reading and computer work. Unlike some CFL bulbs I've used in the past, these don't have a noticeable flicker and they turn on almost instantly, with minimal warm-up time to reach full brightness. I've had the first bulb installed for several weeks now, and it's performing flawlessly. The rest of the pack is ready to go when I need them. Pros: Perfect Fit: The G24Q-1 base fits my fixture exactly. Great Brightness: The 5000K bright white light is excellent for tasks. Instant On: Minimal warm-up time, which is a big plus for CFLs. Value: The 4-pack is an outstanding deal. Cons: • None: I have had zero issues with these bulbs and they have exceeded my expectations. I highly recommend these KOR CFL bulbs for anyone needing this specific base type. They are an outstanding, reliable, and cost-effective lighting solution.

This time I bought 2 4 packs. They are reasonably priced and work well. I would recommend them to anyone who has an apartment that uses these tubes in every room except the kitchen.

I used this product for my hall I needed 2 bulbs the product arrived with one smashed to pieces the product was not packaged properly just a price of white paper in the box

Ripoff! The lamp is 130mm long NOT the 123mm in the drawing on the Amazon page.. -Actually a bit more than 130mm. Size matters as these lamps were produced to fit into measured fixture areas based on the original lamp size. Does not go into my Luxo fixture. DO NOT PURCHASE unless you have a much longer space available. See the attached with this lamp sitting on a metric ruler.
