This is for the 13W S8313 5000K daylight bulb. I'm using it to replace a 13 watt OttLite with magnetic ballast, model T13330, letter A. It fits perfectly and works the same as the much more expensive Ott Lite bulb which doesn't seem to be sold anywhere. In an email from Ott-Lite customer service I was advised to buy a 5000-6000 Kelvin natural lightbulb and this one did. I use this lamp where color matching is very important, i.e. a fluorescent lamp is required. It really is just as good as the original, which costs around $40, and this one is under $8. I'm happy, happy
