I'm really happy with them so far other than the power supplies. I had one burn out and when I got ahold of customer service they informed me that max spect has developed a more rugged cooler running power supply and they are shipping me not just one to replace my burnt one but all four new style supplies. They are back ordered but I still can't complain because I got an answer in about 24hrs. The versatility of these lights us incredible as well. They have other led chips for them such as a fiji purple which I plan to try out
