Bought this 3000K bulb to replace a 2700K one in a desk reading lamp. 2700K bulbs are described as "soft white" and it's the yellow-ish color that's responsible for the softness. Higher temperature bulbs have increasing amounts of blue (5000K bulb may look slightly blue) that balances out the yellow and makes for a whiter but increasingly harder and contrasty light. This 3000K bulb produces a warm white but still soft light (still has a tinge of yellow to it) which is exactly what I want for a reading lamp at home. Did not buy the 3500K as I think it lacks the yellow needed for softness.
Good name-brand product

Quick service

Saved a trip to Lowe's and $$$ in the process.

What is not to like?
This Sylvania 21137 bulb is a replacement for a dual tube fluorescent in a Panasonic bathroom fan. The original Panasonic bulbs were fantastic with instant on and zero flicker. Unfortunately those bulbs are no longer available. I have tried other, similar dual tube bulbs, but the flicker was terrible.
This Sylvania bulb does flicker, but only 3-4 times before it is fully on. It's not perfect, but it does the job. If I need to purchase another replacement it will be this bulb - or I'll try an LED.
