Listings show low-power options such as 13 W for a compact fluorescent (CFL) and 4.0 W for an LED. Product descriptions often present the low wattage alongside an incandescent equivalent (for example, a 13 W CFL or a 4 W LED marketed as a 40 W replacement).
Dimming capability varies by product: some listings state full-range dimmable operation, while others are listed as non-dimmable (on/off only).
It depends on the bulb type: compact fluorescent listings may indicate the presence of mercury, while LED listings are noted as containing no mercury.
Listings commonly report a CRI around 80; some specify '>80' while others simply list CRI 80.
Reported bulb life varies by listing: one LED listing shows an estimated life of 15.1 years, while at least one CFL listing does not include a life estimate.
