Smart Bulb Vintage Style (ST19 Edison)

Vintage Aesthetics Meet Smart Technology

The Smart Bulb Vintage Style combines the nostalgic warmth of a classic Edison filament bulb with modern smart home connectivity. The amber-tinted glass envelope and visible LED filament array recreate the iconic look of early 20th-century incandescent bulbs, while the integrated Wi-Fi module enables app control, voice assistant integration, scheduling, and dimming without requiring a smart dimmer switch. The ST19 shape fits standard E26 sockets and is compatible with most pendant, table lamp, and wall sconce fixtures.

Optical & Electrical Performance

The amber-tinted glass envelope filters the LED output to achieve a 2200K color temperature with CRI > 90, closely matching the spectral output of a vintage carbon-filament incandescent bulb. The visible LED filament array creates the iconic Edison aesthetic while delivering 80 lm/W efficacy, a 9x improvement over a 60W incandescent (8.3 lm/W). The integrated driver maintains constant current across the full dimming range, ensuring flicker-free operation per IEEE 1789 recommended practices (flicker index < 5%, flicker percentage < 10%). The Wi-Fi module operates on the 2.4GHz band only (not compatible with 5GHz networks) and supports WPA2-PSK encryption. Setup is via Bluetooth Low Energy, after which the bulb connects directly to the home Wi-Fi network without requiring a hub or bridge.

Construction & Compliance

UL listed per UL 1993 (self-ballasted lamps and lamp adapters). FCC certified per Part 15 Subpart B (unintentional radiators). Energy Star certified. RoHS compliant. California Title 20 compliant. The bulb is not for use in fully enclosed fixtures, recessed cans, or outdoor wet locations (rated for dry and damp locations only). Compatible with standard E26 sockets in pendant lights, table lamps, floor lamps, and open wall sconces. The amber glass may cause slight dimming compared to clear glass bulbs of equivalent wattage.

Single bulb per package. 2.4GHz Wi-Fi network required (not compatible with 5GHz). Smart features require download of companion app and account creation. Voice control requires compatible voice assistant device. Not for use in fully enclosed fixtures. 2-year limited warranty.
