Product Overview

COB LED Strip, CCT Series, 640 LEDs/m is dot-free COB strip at 640 LEDs/m, 24 V, 800 lm/m, Ra > 90, cut every 25 mm. 640 emitters a metre under a single phosphor line, so a cove reads as a continuous bar of light with no dotting, at Ra > 90. The specification below is reproduced from the manufacturer's own published sheet for this model: DC 24 V input, 8 W per metre, Not published and a published cascade limit of cut every 25 mm / 16 leds. Where that sheet publishes no figure, this page says so instead of estimating one.

Key Benefits

Published efficacy of 100 lm/W, so the wattage behind a given face area can be calculated before the sign is built rather than after.
Cascade limit published as cut every 25 mm / 16 leds, so the run length and the feed points are known at drawing stage.

Who It Is For

Sign fabricators building channel letters and 3D luminous characters who need the depth figure before they cut the return.
Light box manufacturers sizing the module pitch against the face material.
Signage distributors who have to hold a range that covers shallow and deep cavities from one supplier.
Installers retrofitting an existing fascia where the cavity depth is fixed and the module has to fit it.

Problems It Solves

A face that shows the module pattern because the module was specified for a different depth than the sign actually has.
A run that is bright at the feed and dim at the far end because the cascade limit was never published by the supplier.
Condensation inside a sign cavity reaching an unsealed module body.
Two batches of the same model that do not match in colour on the same fascia.

Application Scenarios

Retail fascia lettering on a shop front.
Illuminated light box panels on a building entrance.
Three-dimensional luminous characters on a building parapet.
Advertising plastic characters of the kind this factory has specialised in since 2012.

Use Guide

Work out the run length from the cascade figure: cut every 25 mm / 16 leds. Beyond that, voltage drop starts to dim the far end and power has to be reintroduced.
Size the power supply from 8 W per metre multiplied by the module count, then leave headroom rather than running a driver at its rated ceiling.

Quality Control

Modules are potted and sealed before the ingress rating is verified, not after assembly into a sign.
Colour binning is checked against the published bin so cartons shipped months apart still match on the same fascia.
Every batch is aged before packing; the aging rack is photographed on the factory's own process board.
Finished modules are packed in anti-static bags and cartoned to the published quantity so the count on the box matches the count on the order.

Materials

Injection-moulded housing with the optic moulded in, rather than a lens glued on afterwards.
Potting compound filling the cavity around the board, which is what carries the IP rating.
Pre-tinned lead wires on both ends for cascading, cut to the published module pitch.
3M backing tape on the models where the specification lists it, for direct mounting to the inside of a return.

Manufacturing Process

['Patch', 'A misplaced die shows as a dark lens once the face goes on.', "SMT placement of the emitters onto the module board, photographed as stage one on the factory's own process board."]
['Solder wire', 'A cold joint at the lead is the most common field failure in cascaded modules.', 'Lead wires are soldered and strain-relieved before the housing is closed.']
['Injection moulding', 'A lens bonded on after the fact separates in the heat cycle of a south-facing sign.', 'The housing and the optic are moulded together, then the cavity is potted.']
['Testing', 'A module that only fails under load passes a visual check.', 'Electrical test under load before the module leaves the line.']
['Back glue', 'Tape applied to a contaminated surface releases in the first summer.', '3M backing tape is applied to a cleaned housing on the models specified with it.']
['Aging', 'Infant mortality in LEDs shows in the first hours, not the first year.', 'Finished modules are run on the aging rack before packing.']

Certification Standards

Production follows CE, RoHS, LVD, IP68 test report, UL. Certificates are sent per product on request rather than posted publicly, because the documents a shipment needs depend on the destination market.

Customisation Options

Colour temperature selected per order from the published options rather than held as one stock colour.
Lead wire length and module pitch cut to the sign layout instead of a default spacing.
OEM and ODM work: the source site states that OEM and ODM are supported for customers in all markets.
Packing quantity per bag and per carton adjusted to how the modules will be issued on the fabrication floor.

Comparison

How It Compares With The Alternatives

A technical comparison against other ways of solving the same problem. Nothing here is a performance claim against a named competitor product.

Against a module sold without a published depth band	The depth band is the figure that decides whether the face lights evenly. This model publishes Not applicable. A supplier who publishes only lumens is asking you to find that band by building the sign.
Against a module with no stated cascade limit	This model publishes Cut every 25 mm / 16 LEDs. Without that number the feed points are guessed, and the symptom - a fascia that dims towards one end - looks like a bad batch rather than a wiring decision.
Against an IP rating quoted for the range rather than the model	The rating here is Not published, published against this model. Note that it covers the module body as supplied and not the joints made on site.
Against another family in this range	See the LED Strip and Neon Flex page for what this family does that the others do not, and the related products below for the nearest alternatives.

Questions

COB LED Strip, CCT Series, 640 LEDs/m Questions

How many COB LED Strip, CCT Series, 640 LEDs/m modules can run from one feed?

The specification publishes cut every 25 mm / 16 leds. Past that limit voltage drop dims the far end of the run, so power is reintroduced rather than the run extended.

What is the ingress rating?

The manufacturer does not publish an ingress rating for this product, so none is stated here. Ask before specifying it for an outdoor position.

What is the warranty?

The manufacturer publishes no warranty figure for this product. Confirm it in writing with the order rather than assuming the five year figure that the module range carries.

Can it be supplied in a colour temperature that is not listed?

The published colour options are: cob, tunable cct. Anything outside that list is a custom request and is confirmed in writing before the order, not assumed.
