Bought to replace LED Tubes about 4 years old. Old ones ran really hot and would start flickering and die. The end caps were plastic and 2 broke removing tubes from fixture. These have aluminum endcaps. They also do not have a aluminum ribbed back like old ones had, that got really hot, no blister, but not far from it.Would be 5 star, except they look warmer then tubes already there.Question if really 5000 Kelvin :-)
