Of course not suitable due to their shape and dimensions for all lamps. Fills me exactly the reflector trough my Recessed Spotlights from (may be different in other emitters -> Dimensions note). Compared to other LED lamps in bulb shape with the same wattage subjectively significantly brighter (the complete luminous flux radiated directly downwards and must be reflected as piston bulbs not only). Light color colder than halogen, but for my application in the bathroom fine. Note - not with 11 sqm added very large - 5 of these lamps light up my bath excellently made. The design is optically used to, but in my view not disturbing.
