Product information

Description & Specifications

This C9 option is intended for projects that prioritize a soft, traditional illuminated appearance and an opaque lens when the system is switched off.

The milky lens diffuses the light across the bulb surface while the E17 format integrates with a project-matched commercial C9 socket line.

It is supplied as part of a professional lighting configuration. Lamp color, socket line, spacing, wire, plugs, control method, and replacement quantity are confirmed together.

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

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.

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.
