Overheats easily...

So I bought this Oct 2017 and have been using it for my makeup gigs. The light itself is nice and bright but if you leave it on for a while and shut if off, it will need to cool down before you can turn it back on. Now I have had it for about 1.5 years and I turned it on just to find that it will turn on for a second and right off. I checked all the connections and swapped the fuse. Still not turning on and staying on....What the heck??? I don't know if I should buy another bulb and replace or just buy another ring light...
