They will make your tank look yellowish to orange. Some might like that, I think it looks extremely ugly. Plants get used to many sorts of light, so let your personal preference be the deciding factor. I guess you could mix them with other bulbs.
I like a mixture of 10,000K, 6500K, and pinkish plant grow bulbs best. Everyone is different. :icon_wink
