"these are good but the light is not "clear" it is yellow, which is what you get with incandesent. for true white light and full color spectrum you need flouresent. and if you want plants to grow do not buy green, or red!! these colors will kill your plant. these are two colors that are not absorbed in photosynthesis, so they reflect. that is why plants are green, they do not absorb green light. if you want your plants to grow like madness, buy a BLUE light. this is the color of light they absorb the most."
