Light intensity drops quickly
I have been using the F20T12CW for plant growth. I have been very disappointed that several of the bulbs have quickly deteriorated in light output. A number of these dropped to less than 20% of normal output in less than 1,000 hours of use. Normally, I will get closer to 20,000 hours of high intensity.
