What to know before buying

Listing details to confirm

Listing details are inconsistent: dimensions appear as 15.5*51mm, 15.5*51mm in the caution text, and 16W x 44H millimetres, while the title and details disagree on 40W-50W versus 40W halogen equivalence. The stated voltage also varies between 240 Volts and AC 220-240V. Confirm the bulb size and your fixture's voltage requirements before purchase. The listing warns that humid environments may cause a short circuit and fire, so do not treat its general outdoor-use entry as confirmation of suitability for damp locations.

Who is it for?

Buyers seeking a listed six-pack for compatible decorative, ceiling or cabinet lights.

Less suited to

Customer feedback reports positive experiences with these bulbs as halogen replacements, particularly their warm-white glow, fit and perceived longevity. That may matter for buyers replacing several G9 lamps, but feedback does not establish the conflicting dimensions or resolve compatibility for an individual fixture. Aggregate ratings are mostly five-star, with a smaller spread across lower ratings, and do not explain the reasons behind those ratings.
