You may want to look at the spec. of the bulbs (usually stated on the box). Look for the color temperature. It may be written something like 5000K, 6000K etc.. Your yellow bulb may have temp color around 5000K. If you want something closer to white, you want to get a bulb with color temp. between 6500K to 10000K. The 10000K will have bluish tint and the 6500K may have a slight greenish/yellowish tint. I know that the 6500 and 6700 are good for plant. Not really sure about the 10000K. I would think it should be ok too.
