Placed my order for reefradiance new 360 fusion led setup. From all I have be reading everyone seems very happy with the reefradiance product in general. My concern is how long will led chips last before their lighting quailty starts decline? I read they will last 50,000 hrs. Really? And as far as reefradiance fixtures can anyone testify to how long they have had their reefradiance fixture and how is it holding up. Thank you
