Ok folks... no changes for this year ... we are still going with our Osram things from last year. After all they've done fairly well. The only thing we are changing is to put them lower above the seeds at the moment. Picture to follow once this site update is done. The light color of the tubes is said to be 77 and they are manufactured by Osram. Our babies rock'n roll during daylight time from 6AM - 9PM and enjoy their well deserved sleeping break from 9PM to 6AM.
