Full color (RGBW)

Color-capable fixtures like Ketra do saturated color as well as white. These scenes color the downlights, cove, shelf tape, accents and the landscape.

Gallery wall

Each painting has its own full-color art light. Vibrancy tunes the light's spectrum to bring out the color in the art, the way Ketra's vibrancy setting does.

Vibrancy 0%

In-grade uplights on the specimen trees, path lights, a pool light, and an open-air pool house with a bar, a TV and 1" core-drilled uplights grazing the stone columns. All 2700K.

Bulb & base field guide

The ones that cause reorders

Lamp shape	Base	Voltage	Where you see it	Watch for
A19	E26 medium	120 V	Table lamps, general fixtures	Check the fixture's max wattage and enclosed-rated label.
BR30 / BR40	E26 medium	120 V	Recessed cans	BR40 won't fit most 5" cans.
PAR20 / 30 / 38	E26 medium	120 V	Track, outdoor flood, tall ceilings	PAR30 comes in short and long neck. Measure the can depth.
B11 / CA10 candle	E12 candelabra	120 V	Chandeliers, sconces	E12 vs E14 (European). They look alike and don't interchange.
MR16 shape	GU10 twist-lock	120 V	Track heads, small recessed	Same shape as the 12 V MR16, different base.
MR16	GU5.3 bi-pin	12 V	Low-voltage track, landscape	Needs a transformer. LED flicker usually means the transformer isn't LED-compatible.
G9 capsule	G9 loop pin	120 V	Small glass pendants, vanity bars	Many LED G9s are too long for tight glass shades.
G4 capsule	G4 bi-pin	12 V	Puck lights, cabinet, some landscape	Pin spacing differs from GY6.35. Check before ordering.
