Ses provided along with this info:
I usually buy SKB13EAPDL CF / A-Shape 13 Watt Day Light ($8.05)
I always get bulbs with 5000K or higher--closest to natural full spectrum light. I used to be bothered by the yellowish green color myself. It doesn't cost any extra for a higher Kelvin rated bulb.
Test: USB 3.0 and USB 2.0 in comparison
