Here I get 10 G9 halogen lamps for the same money I otherwise for one or at best two pay (7,69 Euro without shipping, which changes depending on the provider and the time constant). All ten of them came with no glass breakage with me. The light output is in direct comparison to the more expensive lamp not strikingly different (no idea how much lumen, and what color of light). However, if the part you look more closely, is immediately the cheaper design. I pretty sure therefore assume that life will not be nearly as good as that of comparable brand products. Is me but for the price no matter and I also did not expect.
