Ellies/Elsat
How can we trust Ellies on the warranty

I tested various makes, some makes are only 50% out, but Ellies is more than 400% out. How can we trust the claims of 50.000 hours, 15 years etc. The basic reason, why one buy an LED bulb is to save energy.and money on electricity bills. I feel cheated and will only buy those makes, which are within reason out.of spec.
