Luminaire Supply for Contractors

Luminaire supply for contractors means technically matching the luminaires on a plan or bill of quantities, quoting them for the specific project and sending them to site tested. No price list is used; the quote is prepared from your plan or takeoff. Driver and control compatibility, emergency kits, track lengths and mounting details are settled at the quotation stage.

What should be sent for a quote?

The more complete this list is, the more exact the technical matching.

  • Plan: Architectural or ceiling plan (DWG or PDF); luminaire symbols in the electrical drawings if available.
  • Bill of quantities: Room, luminaire type, quantity, wattage and a reference model if any.
  • Ceiling and mounting: Ceiling type (suspended, concrete, timber), ceiling height, recessed, surface or pendant mounting.
  • Control system: DALI, 1-10V, Triac, Switch DIM or on/off; grouping and scene needs.
  • Light values: Colour temperature, CRI, beam angle and target lux if any.
  • Emergency lighting: Which luminaires need an emergency kit, and 1-hour or 3-hour duration.
  • Environment: Areas needing an IP rating: wet areas, outdoors, dusty production areas.
  • Track system: Single-phase, three-phase, DALI or 48 V magnetic track; total track length and run plan.

Driver and control compatibility

Control options vary by model and are stated on the product page and datasheet. Please state the control system on site at the quotation stage.

ProtocolHow it worksOn site
DALI (IEC 62386)Digital and two-way; each luminaire is addressed individually, with driver fault and status reported back.One line supports 64 addresses; larger jobs need several lines and a gateway. Wiring is polarity-free.
1-10VAnalogue and one-way; luminaires on a line dim to the same level.No fault feedback. Luminaires on a line follow the same scenario.
TriacMains-side dimming with a phase-cut dimmer.Compatibility of dimmer and driver is checked before the quotation.
Switch DIMOn, off and dimming from a push-button.Check during commissioning that luminaires in a group stay at the same level.
WirelessWireless control option, depending on the model.Considered in refurbishments where a new control line cannot be pulled.

What makes the work on site easier

  • Emergency kit integration

    A 1-hour or 3-hour emergency kit is integrated into the luminaire; emergency kits for existing LED luminaires are also available.

    Emergency kits
  • Track systems

    Single-phase, three-phase, DALI and 48 V magnetic track; power feeds, connectors, corners, adapters and suspension parts.

    Track systems
  • Pre-shipment burn-in test

    Luminaires are energised and operated before shipment, so LED, driver and connection faults are caught before reaching site.

    Quality and tests
  • 3-year warranty

    The luminaires carry a 3-year warranty; the scope is stated in the product datasheet.

    Datasheets
  • Mounting details and wiring diagrams

    Mounting details and wiring diagrams are shared with the installer; technical support is provided for layout and connection details during installation.

    Installation support
  • Documents

    The luminaires are manufactured in line with the LVD and EMC directives and carry the CE mark. Datasheet and drawing PDFs are on one page, by category.

From bill of quantities to delivery

  1. 01Receiving the filesThe plan and bill of quantities are sent to info@harmonyels.com or through the contact form.
  2. 02Technical matchingLuminaires on the list are matched with catalogue products by wattage, luminous flux, optics, CRI, IP and control. If the list names another brand, the values are compared and an equivalent is proposed.
  3. 03Calculation (if needed)If a luminaire changes or the illuminance target must be documented, a DIALux or Relux calculation is prepared.
  4. 04QuotationA project-specific quote is prepared with a luminaire schedule, datasheets and driver and control notes.
  5. 05Production, testing and shipmentLuminaires pass a burn-in test; mounting details and wiring diagrams are shared with the site team.

How do you verify the quantity?

The 3D Light Planner gives the luminaire quantity, power, plan and, for track spotlights, the track length for the room size. It suits early takeoffs. For jobs that must be documented to the standard, the calculation is verified in DIALux or Relux.

Frequently asked questions

What information should I send for a quote?

A plan or bill of quantities, ceiling type and height, luminaire type and quantity per room, control system (DALI, 1-10V, Triac), colour temperature, CRI and beam angle, emergency lighting needs and areas requiring an IP rating. If a track system is used, add the total track length and run plan.

Can I get a quote if my bill of quantities is incomplete?

Yes. Missing information is clarified during technical matching; exact values are stated at the quotation stage.

My bill of quantities names another brand. Can you offer an equivalent?

Yes. The wattage, luminous flux, optics, CRI, IP and control values of the listed luminaire are compared with our catalogue products, and a suitable equivalent is stated in the quotation. If the illuminance target must be documented, the calculation is repeated in DIALux or Relux with the proposed luminaire.

Are the luminaires tested before shipment?

Yes. Luminaires are energised and operated before shipment, so LED, driver and connection faults are caught before reaching site.

How long is the warranty?

The luminaires carry a 3-year warranty. The scope is stated in the product datasheet.

How many luminaires fit on one DALI line?

One DALI line supports 64 addresses. If the total exceeds 64, several lines or a gateway are planned.

Can an emergency kit be integrated into the luminaire?

Yes. A 1-hour or 3-hour emergency kit is integrated into the luminaire. Separate emergency kits for existing LED luminaires are also available.

Are mounting details and wiring diagrams provided?

Yes. Mounting details and wiring diagrams are shared with the installer, and technical support is provided during installation.
