For lamp:
It lights up from an acceptable range, with a mirror version even more (to 50cm distance approximately 60x60cm without mirror version).
I use them for growing Ficusen (or the majority of them), and it works. This should, however, said: Without proper sunlight it does not work very well and takes just 4 week, however, with only Sonne 2 weeks with suns and lamp just one a week. Irradiation with 10h per day on a timer.
Is ok for the price!
