LED Display Change Orders: Budgeting Pitch, Cabinet and Quantity Changes

Quick answer

Treat a post-order pitch, cabinet format or quantity change as a revised configuration, not a simple line edit. Price depends on pixel pitch, screen or wall size, cabinet quantity, control system, spare modules and freight. Fix a written change-order procedure before production, and ask EagerLED to re-quote the exact revised configuration.

A Post-Order Change Is a New Configuration

Once an order is placed, a change to pixel pitch, cabinet format or quantity usually changes the quoted configuration. The supplied EagerLED pages tie price to pixel pitch, wall or screen size, cabinet quantity, control system, spare modules and shipping or freight for EA500C6, EA250WH5, EA640H1 and EA1000H9. That means the revised order should be priced from the new configuration rather than an estimated percentage added to the original total.

The product pages also show that the configuration is model-specific. EA500C6 uses 500×500 mm cabinets in indoor P1.56–P3.91 or outdoor P2.6–P3.91. EA250WH5 is a 30 mm ultra-thin indoor wall built from 250×250 mm modules in six cabinet sizes and seven pitches from P1.25 GOB to P3.91. EA640H1 is a 640×480 mm front-service indoor wall in P1.25 to P2.5. EA1000H9 is a 500×1000 mm rental cabinet with eight 250×250 mm modules, indoor P1.56–P3.91 or outdoor P2.6–P4.81. A change across any of these boundaries is a different build.

Pixel Pitch Changes Affect Modules, Brightness and Spares

Changing pitch changes the modules and often the spare-module SKU. On EA500C6, GOB is listed on indoor P1.56, P1.95 and P2.6, and the source says to confirm the exact model and matching spare modules rather than assuming GOB is included on every pitch. On EA640H1, GOB is used on P1.25, P1.53, P1.86 and P2, while P2.5 uses a standard SMD2020 module. Those differences matter when the revised pitch is quoted and when spares are ordered.

Brightness can also change with pitch on the quoted model. EA250WH5 lists 600 cd/m² on P1.25 and P1.56 and 750 cd/m² from P1.95 to P3.91, all at 160° and at least 3,840 Hz. EA640H1 lists 600 cd/m² on P1.25 to P1.86, 700 cd/m² on P2 and 800 cd/m² on P2.5, with a 140° viewing angle and at least 3,840 Hz. A pitch change after order should therefore trigger a revised module line, a revised spare-module line and a new brightness and refresh check, not only a price adjustment.

For budget purposes, treat the change as a pixel pitch upgrade and ask for an itemized revised quote. The revised quote should name the new pitch, module, cabinet, quantity and spare modules. If the project also needs a different indoor or outdoor model, that is a separate change: EA500C6 indoor models are IP31 and should be specified for indoor venues, while outdoor projects need an outdoor model with confirmed front and rear protection.

Post-Order Change Decisions and Quote Evidence

Cabinet Format Changes Alter Cabinet Count, Modules and Mounting

Cabinet format changes affect how many cabinets the same wall needs and how the modules are arranged. EA500C6 uses a 500×500 mm cabinet, and each cabinet covers 0.25 m²; spare cabinets are additional. EA250WH5 uses the same 250×250 mm module across six cabinet formats, from 500×250 mm up to 1000×500 mm. EA640H1 uses a 640×480 mm cabinet carrying six 320×160 mm modules. EA1000H9 uses a 500×1000 mm cabinet with eight 250×250 mm modules and can bolt to the 500×500 mm EA500H9 horizontally and vertically on the same 250 mm module grid.

Mounting and service also change with format. EA250WH5 supports wall-mounted, suspended and column installation, and its modules, power supplies and control components are reachable from the front with a suction tool, so no maintenance aisle is needed behind the wall. EA500C6 has optional curve locks for concave or convex arcs and an openable rear cover for maintenance. EA1000H9 has front and rear service access, a detachable power box and optional arc locks that index each cabinet to a set angle; the source says to order the arc locks together with the cabinets.

A cabinet format quotation should itemize the exact cabinet and module identity, quantity, service route and mounting method. For EA500C6, the source says an itemized quote should identify the controller, spare parts, rigging, flight cases and freight. If the format change also changes the layout from flat to curved, right-angle or column, confirm that the revised drawing and cabinet count match the new geometry; a flat-face count does not establish a curved-layout quantity.

Quantity Changes Affect Control, Power, Freight and Spares

Increasing or reducing quantity changes cabinet count, control capacity, power scope and freight. EA500C6 states each 500×500 mm cabinet covers 0.25 m² and spare cabinets are additional. EA250WH5 price depends on pixel pitch, wall size, cabinet quantity, control system, spare modules and shipping. EA640H1 asks for wall width and height, viewing distance, preferred pitch and delivery address, then an itemized quote covering cabinets, controller, spare modules and freight. EA1000H9 price depends on pixel pitch, screen size, cabinet quantity, control system, spare modules and freight.

Power sizing should be rechecked when quantity changes. The EA640H1 source lists average consumption of 100 W/m² and maximum consumption of 300 W/m² across all five pitches, and says to size supply, cabling and any UPS on the maximum figure rather than the average. The EA1000H9 source gives the same instruction for generator, distro and cabling on its indoor and outdoor models: use the maximum figures, not the averages. A larger cabinet quantity changes the connected load even if the pitch and cabinet format stay the same.

Spares should be re-scoped with the revised quantity. EA640H1 says to order spares in the same pitch to keep brightness and color even. EA500C6 says to confirm the exact model and matching spare modules; the indoor specification lists GOB on P1.56, P1.95 and P2.6, so a spare module for one of those pitches should not be assumed to match a different pitch. For later expansion, confirm compatibility before combining cabinets: EA500C6 and EA1000C6 support vertical mixed splicing, but the source says to confirm matching pixel pitch and configuration before combining them.

Control, Mounting and Freight Are Separate Change Lines

Control, mounting and freight should not be hidden in a revised cabinet price. EA500C6 quote guidance asks for an itemized quote that identifies the controller, spare parts, rigging, flight cases and freight. EA640H1 asks for an itemized quote covering cabinets, controller, spare modules and freight. EA1000H9 says the price depends on the control system, spare modules and freight, and is quoted per project. Those are separate lines to re-price when a change order is raised.

Freight and site inputs also need updating. EA500C6 asks for screen dimensions, venue type, viewing distance and delivery city. EA250WH5 asks for screen dimensions, viewing distance and delivery city. EA640H1 asks for wall width and height, viewing distance, preferred pitch and delivery address. EA1000H9 asks for width, height, viewing distance, indoor or outdoor use and the delivery city. A quantity or cabinet-format change alters these inputs, so the revised freight scope should be quoted on the new dimensions and delivery details.

If the layout becomes curved, ring or column, confirm the hardware in the same change order. EA1000H9 arc locks are ordered together with the cabinets and can index a curve or ring; curved and flat sections can be mixed inside one screen. EA500C6 optional curve locks let cabinets form inward or outward arcs, and the source says to specify the required screen layout when requesting a configuration. Those lines belong in the revised quotation, not added later.

Set a Written Change-Order Procedure Before Production

Our purchasing advice is to fix the change-order procedure before production begins. Freeze the exact model, pixel pitch, cabinet format, module footprint, quantity, spare plan, control scope, mounting or rigging method and freight terms. Define who may approve a change, what evidence is required and the last point before production when a change still avoids rework. This is our recommended workflow, not a claim about EagerLED’s internal process.

Use the revised itemized quote as the approval document. For EA500C6, request the controller, spare parts, rigging, flight cases and freight on separate lines. For EA640H1, request cabinets, controller, spare modules and freight. For EA1000H9, request the itemised quotation including spares and shipping. For EA250WH5, confirm pixel pitch, wall size, cabinet quantity, control system, spare modules and shipping. If any line is blank, treat it as unresolved rather than included.

Defer production if the revised configuration is not named in writing. A change that alters pitch, cabinet format, indoor or outdoor model, curve or arc hardware, spare modules or control capacity should be re-quoted for the exact revised configuration. For mixed cabinets such as EA500C6 and EA1000C6, the source says to confirm matching pixel pitch and configuration before combining them. For EA1000H9, arc locks must be ordered with the cabinets. Those checks keep the budget tied to a buildable configuration rather than a series name.

Scenario Checks After a Change Order

Buyer checklist

• Freeze the exact revised model, pitch, cabinet format, module footprint, quantity and spare plan before approving production.
• Request an itemized revised quote with separate lines for cabinets, controller, spare modules, rigging, flight cases and freight.
• Confirm GOB or module type for the exact revised pitch, and order spare modules matched to that pitch and cabinet.
• Recheck power and control sizing on the documented maximum figures when quantity changes.
• Confirm curve, arc or right-angle hardware in the same change order if the layout changes.
• Update delivery city, dimensions and viewing distance so freight is quoted for the revised order.

Frequently asked questions

Can I change pixel pitch after placing an LED display order without a new quote?

Treat it as a revised configuration. EA500C6 price depends on pixel pitch, indoor or outdoor model, cabinet quantity and system requirements; EA250WH5 and EA640H1 prices depend on pixel pitch, wall size, cabinet quantity, control system, spare modules and shipping or freight; EA1000H9 price depends on pixel pitch, screen size, cabinet quantity, control system, spare modules and freight. Ask for an itemized quote for the exact revised pitch.

Does a cabinet format change reuse the same modules?

It depends on the model. EA250WH5 uses the same 250×250 mm module across six cabinet formats. EA640H1 uses six 320×160 mm modules per 640×480 mm cabinet. EA500C6 uses 500×500 mm cabinets. EA1000H9 uses eight 250×250 mm modules in a 500×1000 mm cabinet. Confirm module footprint, cabinet count and service route for the revised format.

If I increase quantity, are spare cabinets included?

EA500C6 says spare cabinets are additional. EA250WH5, EA640H1 and EA1000H9 list spare modules as a price factor and ask for spare modules in the quotation, but the revised quote should state whether they are included or separately priced. Ask for spare cabinets and spare modules as separate lines.

Can EA500C6 and EA1000C6 cabinets be combined after a change order?

EA500C6 and EA1000C6 support vertical mixed splicing for varied screen proportions, but the source says to confirm matching pixel pitch and configuration before combining cabinets. Treat that confirmation as a written change-order item.

What should a written change order state before production?

Name the exact model, revised pitch, cabinet format, module footprint, quantity, spare modules, controller, mounting or rigging method, curve or arc hardware and freight terms. Ask for an itemized revised quote so each line is visible. This is our purchasing advice; the EagerLED pages support those as quotation inputs and dependencies.

Do curve or arc locks need to be ordered with cabinets?

For EA1000H9, the source says to order the arc locks together with the cabinets. For EA500C6, optional curve locks let cabinets form concave or convex arcs, and the source says to specify the required screen layout when requesting a configuration.
