white ranger lightning

Common filament shapes in this white-ambiance category are ST19 and A19.

These filament bulbs deliver adjustable white light, from warm/soft tones to cooler, daylight-like tones. That lets you select warmer settings for relaxed moods and cooler settings for task-oriented lighting.

These bulbs produce about 530–550 lumens, consume 7 watts (marketed as a 40‑watt incandescent equivalent), and list a Color Rendering Index (CRI) of 80.

They use a standard Edison medium screw base (E26).

Rated at about 15,000 hours—commonly quoted as roughly 22 years based on typical residential usage—this reflects the expected average lifetime.

Bluetooth supports up to 10 bulbs in a single room. Adding the optional bridge (sold separately) unlocks automations, remote/out-of-home control, and typically provides a more stable connection for larger setups.
