The H7 Ultralife is - compared to a standard lamp - so it can be on the packaging read 3 times longer. Also in comparison to your standard bulb (which is not the lamps with +50%, +60% or even + 90% light output) this lamp disadvantages, ie it lights (some) less bright and (somewhat) less far. This can be seen clearly on the packaging in a nice chart from the manufacturer Osram. The gigantic advantage is the current ridiculous price of two pears, I paid directly from Amazon only about 20% of the price for premium lamps. So: very inexpensive brand lamp with long shelf life (thick filaments that last longer, but not so hot, ie not so bright), but it is necessarily compromising on light output.
