I believe those ones say on their packaging that they are "to highlight indoor plants," which I took to mean that they don't actually put out the range of spectrum that the plants really need. Like was mentioned, if you have 'em, use 'em, otherwise go for the cfl, T5, or T8 6500k style, which are also listed as "daylight."
Can't those damn florescent producers just make it easier for us pepper growers? lol.
