I have personally installed over 30 rgf units (phi not reme) and they work very well when they work.. The failure rate in the bulbs is in my opinion way too excessive. It is not uncommon to replace the bulb every other year which is very pricey. The reme is a different setup and I do not have a track record with it so I cannot comment. I will say one if the running jokes at work is when I get a phone call and the tech says "hey you won't believe it,, I was on a call today and I saw a rgf that was working" they have made changed to ballasts I believe which had helped. I just pass the info and experience I have along
