only hardware store quality (?) away Caution hands

Had testweise 2 bars bought, price is very, very low, therefore skeptical (stinginess is mostly just not cool).
Another advantage of 80 watts instead of 100 watts without large losses in the illumination in my application
Worked well, burning time was (felt) a little shorter than previous brand product, but at the price (!) Absolutely OK
So purchasing the same spare, even cheaper (!) But .... ruckzuck (a few weeks) were blown 2 new bars.
Now is the last in it (other Carge?) When not holding at least 1/2 year wars for me.

Postscript
Seven weeks, that's ok, hands off
