Philips Hue White Ambiance Filament ST19 Review (2027)
Research review of the Hue White Ambiance Filament ST19: Edison tube shape, 550 lumens, tunable white, Zigbee plus Bluetooth.
Philips Hue White Ambiance Filament ST19 (1-Pack)
The Edison ST19 silhouette with tunable white on Zigbee and Bluetooth.
Our verdict
The Filament ST19 is the fixture-first Hue bulb: the long Edison tube shape that exposed pendants and vintage fixtures actually call for, with tunable white instead of a fixed amber. Output is a modest 550 lumens, so it is atmosphere lighting, not room lighting, and it is priced like the specialty item it is.
What we like
- True ST19 Edison tube shape for open pendants and vintage fixtures
- Tunable white across the White Ambiance range instead of one fixed amber
- Zigbee through a Hue Bridge plus Bluetooth for basic control
- 550 lumens is honest output for an exposed filament bulb
What to watch out for
- Tunable range stops well short of deep amber candlelight
- 550 lumens will not light a whole room alone
- Premium price for a single bulb
What owners report: Philips Hue White Ambiance Filament ST19 (1-Pack)
Synthesized from recurring themes in long-term owner feedback.
Most praised
- The elongated tube shape fills open pendants and vintage fixtures the way they were designed to look
- Tunable white in a filament body is rare, letting one pendant shift from task light to evening warmth
- Owners get Hue scenes and schedules in a bulb bought mainly for its silhouette
Common complaints
- The warm end never reaches the deep amber glow that fixed filament bulbs deliver
- Modest output means rows or pairs are needed over a table or counter
- Paying a premium for a single specialty bulb stings when a fixture needs several
Who it is for
Hue owners with open pendants, clear shades, or vintage fixtures in ST19 proportions. Not for main room lighting or deep amber looks.
The shape is the point
ST19 is the elongated teardrop tube of classic Edison bulbs, and in an open pendant an A19 filament looks stubby by comparison. This bulb keeps the silhouette and the visible filament while adding Hue control: Zigbee through a bridge, Bluetooth for basics.
Tunable white, with a floor
Unlike fixed-filament bulbs, the White Ambiance range lets the same pendant run cooler white for tasks and warm white for evenings. The trade: the warm end stops short of the 2000K amber a true vintage filament gives, so candlelight purists should look at the Sengled Edison instead.
Output expectations
550 lumens from 7 W (a 40W equivalent) is right for filament bulbs and wrong for lighting a kitchen alone. Run them in pairs or rows over counters and tables, the way Edison bulbs were always meant to be used.
