Well it?s one of those things you can spend a bunch of money on if you want. Some site sponsors might chime in with their pitch here, but I?ll give you mine. Almost 2 years ago I bought a light bar off eBay for $26, I use it almost daily. It?s never leaked or got condensation and all the leds still work. Now you can spend a few hundred dollars on a expensive set or roll the dice like I did, but I figured if it only lasted a few years I got my money?s worth. So do with that information what you will, you probably won?t get a great warranty or customer service, but can score some lumens for cheap.
