this is true, a lot of newer bulbs now can be mounted in any direction, just have to look on the package and see what they recommend.Bulbs are designed to operate correctly in different positions... (i.e. B/U = Base Up, B/D = base down, HOR = horizontal. Most bulbs are rated @ 10,000 hours. So, if you put a lamps that are rated HOR and the lamp is installed base up it will decrease life expectancy. Good luck on warranty of lamps.
I'm unclear as to why you would need dim-able. Are they dim-able or do they have bi-level switching? ( using 2 capacitors)
