Review on 💡 Highly Efficient Halogen Bulb - Q100CL DC, 120V, 100W by Roger Mitchell

My well made architectural style lamp has never had a problem with lamp contacts melting. The second simply melted and one contact fell off. The packaging says 2000 hours, which in my case was not even close to reality. The first one lasted a little longer than the flash, I hope the rest last longer. Most likely the solder pins are made of solder that is too weak for the intended application. You can find better lights elsewhere.
