Product information

Description & Specifications

This lamp is intended for contractors who want the classic C9 roofline shape without the strong visible LED-dot appearance of a fully clear lens.

The transparent milky lens softens the light point while retaining a clean, defined C9 profile. Its E17 format is selected with a matching commercial socket line for replacement programs or new cut-to-length roofline builds.

This is specified as a system component rather than a consumer decoration bulb. Socket type, spacing, wire, plugs, controls, color, and project quantity are confirmed together before supply.

Published values apply only where the matching reference model is identified. Final electrical, environmental, packaging, and compliance data follow the approved production model.

System compatibility

What This Bulb Works With

Compatibility is checked as a complete installation package, not from the lamp base alone.

Socket line: E17 C9 commercial socket line; spacing selected from the approved roofline layout
Mounting clip: All-in-one clip selected for the lamp, socket orientation, gutter, or shingle edge
Power connection: SPT-1 or SPT-2 male/female quick-connect plug matched to the specified wire
Control: Steady-light circuit with an approved mechanical timer, photocell, or compatible dimmer
Not compatible: Not an addressable RGBW pixel. Choose the RGBW Pixel System when individual-light color control is required.

Reference BOM

12-Inch Spacing Planning Example

At 12-inch socket spacing, planned lamp quantity is approximately equal to the roofline length in feet. Add 5–10% service stock.

Roofline length	Lamps	Matched socket line	Clips	Control / circuit
50 ft	50 + 3–5 spares	50 ft matched socket line	50	Single zone after load review
100 ft	100 + 5–10 spares	100 ft matched socket line	100	Timer/photocell after load review
200 ft	200 + 10–20 spares	200 ft total planned line	200	Split according to circuit plan
500 ft+	Calculated from drawings	Configured from project layout	Calculated from layout	Multi-zone project design

Reference configuration only—not a universal electrical layout. Final circuit loading, maximum run length, wire type, weather protection, and zoning must be approved for the selected components and local requirements.

FAQ

Frequently Asked Questions

Can this bulb be used on an existing C9 light line?

It can be considered when the existing line uses the same E17 base and its voltage, wire type, socket condition, dimmer, and outdoor protection match the approved lamp model. We recommend confirming the complete line before ordering replacements.

How many bulbs are required for a roofline?

At 12-inch socket spacing, the planned lamp count is approximately equal to the roofline length in feet. Add 5–10% service stock. Other spacing options must be calculated from the actual drawing.

Can replacement bulbs be supplied without a complete system?

Yes, replacement-lamp supply can be discussed after compatibility is confirmed. For a new installation, we recommend configuring the bulb, socket line, wire, plugs, clips, and control together.
