So I dabbled in led products for a little bit, the think to know about LEDs are basically the light emiting parts are just little "computer chips" they make huge amounts of them and then test them the better ones get grouped together and put into expensive things the ones that dont have a good light output vs electrical input (meaning more heat output) are destined for cheap things. The things that wear out in LED systems are the drivers, resistors, all the parts that make the damn thing emit light. So when you buy a cheap LED system you are getting a lot of the bottom of the barrel parts. When you are buying mid grade you are getting a mix of cheep and good parts (dont go for fancy named diodes get cheap diodes and expensive drivers). When you buy high end stuff you get highend stuff (we all drive lexuses here we all know what I mean) but you pay for it.
As for inside the rig bulb replacements CHEAP OUT! like seriously if they are on for a long period of time that is not a good sign. Often the max amount of time one would be on is like 40min? Then it would be off again for like hours? (except the LP bulb and that is exposed, would probably buy a good one for that)
