Aqueminianswered grow question 3 years ago MarsHydro lights are very good if used at the proper distance and you keep a fan on them to keep them cool. That will extend the lights life and stop individual LEDs from burning out. I started with a TS600, then went to 2 TS1000, I now use 2 TS1000 and a Master Pursuit 500w CMH from Growers Choice with a 3K-Red bulb for extra flowering power.
Me and a couple of my buddies run Mars lights, we all like them and were impressed, even with the TS600.
I have never used a Philizon, and don't know anyone who has. So no opinion on those, sorry.
