(4 Pack) K22195 - PLS13W/2P/841 - Compact Fluorescent Plug-in - T4 - Single Tube - 13 Watt - 2-Pin (GX23) - 4,100 Kelvin (Cool White)

These KOR compact fluorescent plug-in bulbs are a solid choice for anyone needing reliable lighting replacements. The 4100K cool white color temperature provides a bright and clean light that works great for workspaces, kitchens, and utility rooms. At 13 watts, they’re energy-efficient while still giving off plenty of illumination. I found installation to be quick and easy thanks to the 2-pin GX23 base. They’re also well-packaged, so all four arrived without any damage. The quality feels consistent and each bulb lights up instantly with no flicker. Overall, a great value for a 4-pack of dependable fluorescent bulbs.

These lights are perfect for our apartment complex! They arrived in a timely manner and all work!

These fluorescent light bulbs arrived in very impressive packaging and work great. Very simple to replace the old bulbs. The price of the 4-pack is very reasonable.

Like the four pack. Seems well made.

Much, much better value compared to OttLite or other companies’ replacement bulbs. Was delivered within a day although I don’t have Prime. The bulb fitted my lamp well and was simple and easy to install (using a YouTube video tutorial for guidance). Highly recommended.

These lightbulbs are very good brighten up the area we are installed them. Will buy again they does flicker a little when they come on.

It takes a moment for the bulb to get up to full brightness, but works as expected. Brightness: as expected and comparable to other brands. Make sure you purchase the same color (cool, warm, etc.) as your other existing bulbs or replace all at the same time. Durability: Good. For me, this is a repurchase. I use these lights nightly. For my usage, each bulb will last 1-1.5 years. Quality: comparable to other brands sold at box stores. Cost: The cost of this item has increased since last purchased, but it is still a good value compared to what I would pay at my local stores for the same number of bulbs.

I purchased this 4 pack of bulbs and one was installed in April this year 2025. Today is October 30, 2025 and the bulb just blew out!!! This type of bulb has been used in my kitchen ceiling fixture for over 32 years. I normally purchased this type of bulb from Home Depot but they had none in stock at the time. I purchased this 4 pack from Amazon and for the bulb to blow out in 6 months is cause to not ever make a purchase again if I can absolutely help it. Totally raggedy!!! Home Depot has them in stock and I just purchased 4 bulbs. The average life span of their bulbs is 10,000 hours. There is no way the bulbs purchased from Amazon are 10,000 hours. One bulb usually last us about 3 to 5 years in the kitchen.

Worked well fit perfectly
