For spot lights check out par led . Home depot, fero, kessil, led wholesellers, advanced led. Thats a good company too.
The diodes that burn out is commom with blackstars. Which was the most popular led for a while. I think they are crap.
The apollos I use are modular design. Apollo 10 has 10 modules with 15 led's. If one module goes out the rest still work. Theres a system that lets you know if a diode, driver or fan goes out. Lets you know which one by blinking lights.
Most led's have 3 year warranty. Apache have a 2 year warranty but designed hy nasa and ed rosenthal. Then inda gro imduction lights have a 10 year warranty.
Cidly is in china so if something breaks they will send you the part with instructions to minimize down time. If you are unable to repair with their intruction. They will pay shipping to send it back for repairs or a new one.
Also fero and area 51 have a life time warranty. Area51 is having a holiday sale.
Also almost every company will give discounts for buying multiple lights. Even if just 2 lights.
