This review is from: Satco S8337 2700K 26-Watt G24q-3 Base T4 Quad 4-Pin Tube for Electronic and Dimming Ballasts (Tools & Home Improvement)
One of the lights in my kids bathroom went out, and I needed a replacement. They have 3 lights total in them, and use the Quad tube CFL design. I ordered the bulb, it was shipped quickly, but something I didn't pay attention to was the color temperature. This color temperature was 2700K, which equates to warm white. Well the white is actually yellow, where the other two lights have a white light (maybe 4000K?). It is hard to tell, because color temperatures are not on the bulbs. So I have 2 cool white (white white), and one warm white (yellow white). To match the colors, you should replace all the bulbs.
The quality of the bulb is excellent, and was "plug and play." the bulb was well protected during shipping, and I would order again.
