Lights Keeps Burning Out

[Cody Evans]

Hi fixers,

I hired a handyman to do my electrical and am sure this issue will reoccur again during the future. What I had the handyman do was rewirse 2 sepearate lights into one. Its a 120V circuit. I replaced the dimmer light switch myself but flipped it upside down so my roommates could have it go up and down in the way the other switches in the house are. The new led light installed that morning burnt out. We though lt it was a defective light and so we got the same one again at home depot. In 2 weeks the light burned out again. 

Any ideas on why this would happen and other situations where mt bad electrical work will mess up other parts of the house? I am trying to become more handy for my flips but cant have things blowing out all the time. Could it just be the model of light?
