COB Strip 3mm width 7 W/m

الوصف

The COB Strip 3mm width 7 W/m is a 3 mm LED strip light from the Lightstec COB range, built for professional linear lighting projects. It delivers 7 W/m at DC24V/DC12V with CRI >90, and is available in IP20 protection options. Wattage, CCT, CRI, PCB width, IP grade, reel length and private labelling can be customised for OEM/ODM orders.

Why choose this strip

• ■No dark spot even in most small-size aluminium profiles
• ■High-density flip-chip COB, uniform light from head to tail
• ■IP65 available by silicone extrusion process
• ■Easy to terminate with a wide range of solder-free connectors
• ■CRI >90 with single-bin colour consistency

Product Specification

Dimension & Cutting Unit

The drawings below are the original dimension drawings from the Lightstec catalogue for this model. 3 mm PCB, 5000 mm per reel, red/black lead wire L=120 mm AWG20. Cut only at the marked scissor position: every 41.66 mm at DC24V, or every see drawing at DC12V.

Product Photometrics

Measured at 7 W/m, 25 °C. Luminaire lumens per metre and efficacy in lm/W by colour temperature, transcribed from the Lightstec catalogue.

Dust & Water Resistant

Four protection options are available for the same strip, so one product can cover dry interiors, bathrooms, covered outdoor areas and wet locations. The cross-sections below are taken from the catalogue and show how each option changes the finished profile height.

تثبيت

Keep each continuous strip run below 10 m and wire all runs in parallel from the driver — never roll a long run in series, otherwise the tail end will be visibly dimmer. Select a constant-voltage driver rated at least 20% above the total connected load (catalogue note: 24 V, 10 W/m, 2 m; led power < driver wattage).

• Clean the mounting surface before applying the 3M adhesive; use an aluminium profile for heat dissipation and a perfectly straight light line.
• Cut only at the marked cutting unit, then solder or use the matching 2PIN-8MM connector — do not cut through an LED or a resistor.
• For dimming and colour control, place the controller between the driver and the strips; PWM controllers must match the DC12V / DC24V input.
• Seal both ends with silicone and end caps for IP65 / IP67 installations.

Accessory

A complete set of solder-free connectors, waterproof joiners and smart sensors is available for this 3 mm strip, so the same product can be configured for manual switches, occupancy sensing or outdoor installation. Matching connector code: 2PIN-3MM.

Smart sensor

Quick connector & waterproof connector

• 2PIN-3MM — PCB to cable / PCB to PCB / PCB to PCB with cable / L corner / 90 degree
• 2PIN-3MM-IP65 — waterproof connector for IP65 installations
• Smart sensors — touchless IR, touch dimmer, human IR, door & window sensor, DC12–24V

Profiles

Matching aluminium profiles turn the strip into a finished linear fixture: they dissipate heat, protect the LEDs and produce a perfectly straight, glare-controlled light line. Compatible profile codes: LT-613, LT-508, LT-601, LT-8842A, LT-5878M.

Applications

Seamless linear lighting in shallow aluminium profiles, cove lighting, mirrors, under-cabinet lighting, retail shelving and applications that must show no visible LED dots.
