I haven't received my fixture yet, so I can't really recommend it, but from my understanding it gives off about 30 par on the 24" fixture for a 20g tall, so close to medium light. It all depends what type of lighting you want and your price range. I thought this was a good price for the needs I had, and I personally prefer LED over other fixtures. I also ordered one for my 7.9g cube I'm hoping I'll get medium to high, but I won't know till i see par ratings for that size.
