Tala Sphere I vs Sphere II: E14 and E27 Sizing Guide

Compare Tala Sphere I and Sphere II bulbs by cap size, pack count and Dim to Warm glow, so you pick the right E14 or E27 fit for your fixture.
Quick answer
Choose the Tala Sphere I E14 if your fixture takes a small screw cap and you need three bulbs; choose the Tala Sphere II E27 if it takes a large screw cap and you want five. Both share the same matte white finish, Dim to Warm behaviour and flicker-free design, so cap size and pack count are the real decision.
What actually differs between Sphere I and Sphere II
The supplied catalog facts describe both bulbs in almost identical language: matte white finish, Dim to Warm characteristics and flicker-free behaviour. The meaningful differences are the cap type and the number of bulbs in the pack. Sphere I is supplied as a 3x pack with an E14 cap; Sphere II is supplied as a 5x pack with an E27 cap.
That means this is less a comparison of glow quality and more a comparison of fixture compatibility and quantity. If you are replacing bulbs across several fittings, the pack count matters as much as the cap.
E14 vs E27: the small screw vs large screw bulb difference
E14 is the smaller screw cap, often found on compact pendants, wall lights and decorative fittings. E27 is the larger screw cap used on most standard pendants and larger fixtures. The two are not interchangeable: an E14 bulb will not seat in an E27 holder, and an E27 bulb will not fit an E14 holder.
Check the label inside the lamp holder or the fitting instructions before ordering. If the label is missing, the physical size of the threaded socket is the reliable clue: the smaller thread takes E14, the wider thread takes E27. Do not force a bulb; if it does not start threading easily, you likely have the wrong cap.
Pack size trade-off: three small caps or five large caps
Sphere I comes as a 3x pack and Sphere II as a 5x pack. A larger pack lowers the cost per bulb when you have several matching fittings, but it is wasteful if you only need one or two. A smaller pack suits a single pendant or a pair of bedside lights where you want a spare.
Neither listing supplies dimmer compatibility specifications, wattage or colour temperature figures, so treat those as unknowns and confirm with the fitting or dimmer manufacturer if they are critical to your setup.
Trade-offs to weigh before you buy
- Cap compatibility: Match the cap to the fixture, not the other way round: E14 for small screw holders, E27 for large screw holders. There is no adapter-free way to swap between them. Check every fitting you plan to re-bulb before choosing a pack.
- Pack count vs cost per bulb: The 5x Sphere II pack spreads cost across more bulbs, but only if you have five E27 fittings or accept storing spares. The 3x Sphere I pack is the leaner choice for one or two E14 fittings. Count your E14 and E27 fittings separately; you may need both packs.
- Shared glow, different sockets: Both bulbs offer Dim to Warm and flicker-free behaviour, so you are not trading glow quality for cap size. Pick the cap your fixture needs and let the pack count decide the rest. If you want matching glow across mixed fittings, plan for one pack of each.
