The T30 tubular LED filament lamp occupies a unique position in the decorative LED market. Unlike the globe (G95, G125) or Edison (ST64, A60) shapes that dominate the pendant and cluster fixture market, the T30 is a specialist lamp — designed specifically for fixtures where a slender, elongated light source is part of the design intent. Wall sconces, bathroom vanity strips, linear pendants, and architectural cove lighting all use the T30's distinctive profile as a visual element.

The T30 designation refers to the lamp's shape: T = tubular, 30 = maximum diameter in millimeters (approximately 30mm / 1.2 inches). The lamp is available in multiple lengths — T30/150 (150mm long), T30/200 (200mm), T30/300 (300mm) — allowing it to be matched to fixtures of different scales. The longer versions (T30/300) are particularly popular in bathroom vanity strips, where a row of T30 lamps creates a continuous line of warm light across the mirror.

This guide covers the technical specification of T30 LED filament lamps, the fixture applications where they are most commonly specified, and the bulk procurement process for commercial buyers.

T30 Technical Specification

Physical Dimensions

Model	Length (mm)	Diameter (mm)	Base	Weight (g)
T30/150	150	30	E14 or E27	35
T30/200	200	30	E14 or E27	45
T30/300	300	30	E14 or E27	65

Base note: T30 lamps are available with E14 (small Edison screw) or E27 (standard Edison screw) bases. E14 is more common for T30/150 and T30/200 in European markets; E27 is more common for T30/300 and in North American markets (E26 equivalent). Specify the base type at order placement.

Filament Configuration

T30 lamps are available with two filament configurations:

Straight filament: A single straight filament running the length of the lamp. This is the most minimalist configuration — the filament appears as a single glowing line when the lamp is illuminated. It is the most popular configuration for contemporary minimalist interiors.

Spiral filament: A helical filament that winds around the lamp's central axis. The spiral configuration produces a more complex, visually interesting light pattern and is preferred for applications where the lamp is viewed from the end (e.g., in a horizontal wall sconce where the lamp's end is visible to the observer).

Double straight filament: Two parallel straight filaments running the length of the lamp. This configuration produces higher lumen output than a single straight filament at the same lamp length, and is used in applications where higher light levels are required without increasing lamp length.

Glass Envelope Options

T30 lamps are available with three glass envelope options:

Clear glass: The filament is fully visible through the clear glass envelope. This is the standard option for minimalist applications where the filament's visual quality is part of the design intent.

Smoked glass: A light grey tint that softens the filament's appearance without significantly reducing light output (typically 5–10% reduction). Smoked glass is preferred for applications where the lamp is viewed at close range (e.g., bathroom vanity strips) and a softer, less intense filament appearance is desired.

Frosted glass: A white frosted finish that diffuses the light and hides the filament. Frosted T30 lamps produce a soft, even glow rather than a visible filament. They are used in applications where the lamp's shape is the design element but the filament is not intended to be visible.

Primary Application: Minimalist Wall Sconces

The T30 lamp's most important application is the minimalist wall sconce — a fixture category that has grown significantly in the luxury residential and boutique hospitality markets over the past decade.

The Minimalist Sconce Aesthetic

The minimalist wall sconce is defined by its restraint: a simple geometric form (cylinder, rectangle, or abstract shape) that holds the lamp with minimal visual interference. The lamp itself — its shape, its filament, its warm glow — is the primary visual element. The fixture is the frame; the lamp is the art.

This aesthetic requires a lamp that is visually interesting in its own right. The T30's slender cylindrical profile and straight filament create a clean, architectural quality that is well-suited to minimalist interiors. The lamp's warm color temperature (2,700K or 2,200K) produces a soft, intimate light that is appropriate for residential and hospitality environments.

Fixture Compatibility Considerations

When specifying T30 lamps for wall sconces, verify the following compatibility parameters:

Fixture depth: T30 lamps are longer than standard A60 or G95 lamps. Verify that the fixture's lamp compartment is deep enough to accommodate the T30 length without the lamp tip touching the fixture body. For T30/300 lamps, the fixture depth must be at least 320mm.

Thermal management: Wall sconces are often semi-enclosed fixtures that trap heat around the lamp base. Verify that the T30 lamp is rated for the fixture's operating temperature. Our T30 lamps are rated for Ta ≤ 45°C (standard) or Ta ≤ 55°C (enclosed fixture version). For fixtures with limited ventilation, specify the enclosed fixture version.

Dimmer compatibility: Wall sconces in residential and hospitality applications are almost always dimmed. Verify dimmer compatibility before specifying. Our T30 lamps are tested for compatibility with Lutron Caséta DVCL-153P, DVRF-6L, and RA2 RRD-6ND; Leviton DVCL-153P; and Legrand Adorne ADTP703TUW4.

Bathroom Vanity Strip Applications

The T30/300 lamp is the standard specification for bathroom vanity strips — a row of T30 lamps mounted horizontally above or beside a bathroom mirror. A typical vanity strip uses 3–5 T30/300 lamps at 150–200mm spacing.

IP rating: Bathroom vanity strips in Zone 2 (within 0.6m of the bath or shower) require IP44 minimum. Our T30 lamps are available with IP44 rating for bathroom applications.

Color temperature: 2,700K is the standard specification for bathroom vanity lighting in residential applications. 3,000K is sometimes specified for bathrooms where the vanity is used for makeup application and a slightly cooler, more neutral light is preferred.

CRI: CRI ≥ 95 is recommended for bathroom vanity lighting, where accurate skin tone rendering is important. Our premium T30 range achieves CRI 97 with R9 = 85.
