Quick answer
Choose the Sphere IV if you want a dramatic oversized sphere with dim-to-warm flicker-free light. Choose the Elva E26 if you need a compact, versatile bulb that works in pendants or table lamps and prefer a standard light output.
Size and visual impact
The Sphere IV is deliberately oversized, making it a design statement in open fixtures. The Elva E26 is more compact, fitting easily into smaller pendants and table lamps without overwhelming the shade.

Versatility and options
Elva E26 comes in tinted or non-tinted glass and in multiple pack sizes, giving you flexibility for matching or mixing in a room. Sphere IV is available in two sizes but without tinted options.
