Project applications

Traditional Roofline Lighting

C7 and C9 systems suit residential rooflines, hospitality properties, retail façades, municipal displays, seasonal programs, and installer portfolios that require a familiar, replaceable bulb format. Each project is configured around the building—not sold as a one-size-fits-all consumer string.

  • Custom roofline measurements and run lengths
  • Bulb, socket spacing, wire color, and clip selection
  • Zone, power, control, service, and replacement planning
  • Job-based, wholesale, or private-label supply

Technical planning

Plan the Complete System

Lengths and components are calculated from the site survey, not from a generic package size.

How much light line?

Measure every illuminated edge as a separate run, then add the vertical drops, transitions, service loops, and a practical installation allowance. We turn the elevation measurements into a run-by-run bill of materials instead of estimating from floor area.

How much wire?

Wire quantity includes socket line plus unlit lead wire, jumpers between roof sections, controller or timer leads, and return paths. The final length depends on outlet locations, roof geometry, wire routing, and the number of independently controlled zones.

Which clip?

All-in-one clips are useful for many gutter and shingle edges. Tile, metal, parapet, ridge, masonry, and specialty trim may require a different clip or fastening method. Confirm the mounting surface before the installation package is released.

Which bulb and spacing?

C7 offers a smaller traditional profile; C9 produces a larger, more prominent roofline. Bulb finish, color, output, socket spacing, and wire color are selected together to create the intended appearance and daytime visibility.

Plugs and Lamp Sockets

Use each component for its intended role in the approved project layout.

Use quick-connect plugs

Use compatible male or female quick-connect plugs when a measured SPT lead, branch, or endpoint needs a field-installed connection. Match the plug to the wire type and polarity, keep connections within the approved electrical plan, and protect outdoor connections as required for the site.

Use lamp sockets

Use compatible lamp sockets when building custom-spaced light line or replacing a damaged socket. The socket must match the selected C7 or C9 bulb base, wire specification, spacing plan, and installation environment; replacement parts should be standardized for future service.

Installation workflow

Four Installation Steps

01

Survey and measure

Record every roofline, peak, return, transition, power location, mounting surface, and access limitation. Separate illuminated runs from unlit leads and jumpers.

02

Configure the system

Select C7 or C9 bulbs, socket spacing, wire color, clips, plugs, control method, zone layout, service stock, and project packaging as one compatible specification.

03

Install and align

Install the approved clip for each surface, keep bulbs consistently oriented, avoid pinching the wire, and leave planned service access at transitions and connections.

04

Test and document

Test each run before final handoff, label the zones, document connection points, and retain compatible bulbs, sockets, clips, and plugs for future service.

Project note

Outdoor electrical connections, load limits, circuits, and fastening methods must be confirmed for the selected components, property conditions, and applicable local requirements.

FAQ

Frequently Asked Questions

How is a professional C7/C9 roofline system installed?

Start with a site survey and run-by-run measurements. Select the bulb size, socket spacing, wire color, clips, plugs, controls, and service parts as one system. Install the approved clip for each mounting surface, keep bulb alignment consistent, test every run, label the zones, and document connection points for future maintenance.

How much C7/C9 light line does a project need?

Measure every illuminated roof edge, peak, return, window, column, or landscape section separately. Add transitions and a practical installation allowance. The final light-line quantity should come from the elevation plan rather than the building floor area or a generic kit size.

Which clips should be used for C7/C9 lights?

All-in-one clips work for many gutter and shingle edges, while tile, metal, parapet, ridge, masonry, and specialty trim may need different mounting hardware. The clip must match both the bulb orientation and the actual surface, so confirm site conditions before ordering the project package.

How much wire is required?

Calculate the illuminated socket line plus unlit lead wire, jumpers between roof sections, vertical drops, controller or timer leads, return paths, and service loops. Outlet locations, roof geometry, zone count, load limits, and approved routing determine the final total.

When should quick-connect vampire plugs be used?

Use compatible quick-connect plugs when a measured SPT lead, branch, or endpoint requires a field-installed male or female connection. Match the plug to the wire specification and polarity, follow the approved electrical plan, and protect outdoor connections as required for the property.

When should C7/C9 lamp sockets be used?

Use compatible lamp sockets when producing custom-spaced light line or replacing a damaged socket. The socket must match the selected C7 or C9 bulb base, wire type, spacing, and installation environment. Standardize replacement sockets and bulbs so future service remains simple.

Can existing installers transition to a permanent C7/C9 program?

Often, yes. We can help standardize bulbs, socket line, wire color, spacing, clips, connection parts, controls, job packaging, and replacement stock around the installer's recurring project requirements.
