Ruth's sister 20LED Light Strip Bar 20cm 5500K-6000K 2.5W

SKU CH-9GJY-MTCK3

A 20 cm, 20 LED strip delivering 5500-6000 K light at 2.5 W via micro-USB, with adhesive backing for tool-free mounting

  • Daylight-balanced 5500 K-6000 K output for accurate colour rendering
  • 20 LEDs deliver 20-24 lm at only 2.5 W power draw
  • CRI 70 gives natural tones for studio and close-up work
  • Micro-USB powered so it runs from any 5 V 500 mA source
  • Aviation-grade aluminium body with adhesive backing for tool-free mounting

LED strip bar for tight spaces

The 20 cm aluminium bar holds 20 LEDs that produce a cool-white output between 5500 K and 6000 K. It draws only 2.5 W from a 5 V micro-USB source and is designed to mount in wardrobes, cupboards or tent interiors where a mains socket is not practical. The sponge-glue backing lets you position it without tools and remove it cleanly.

Thermals noise and power

At 2.5 W the strip runs cool to the touch and adds virtually no heat to a small enclosure. There are no moving parts so operation is completely silent. The 500 mA draw at 5 V means it can run from a standard USB power bank or any 5 V USB port without a dedicated adapter.

Build integration

The bar needs a micro-USB cable and a 5 V USB power source, neither of which are included. Its 20 cm length and adhesive backing free up space that a bulkier fixture would occupy, and the lightweight aluminium body adds negligible load to shelves or fabric walls. The 70 CRI output suits general illumination rather than colour-critical work.

Questions about this item

How do I install the 20cm LED strip using the sponge glue, and what step do people often skip?

Clean the mounting surface thoroughly, peel the glue backing, press the strip firmly for several seconds, then plug a micro-USB cable (not included) into a 5 V, 500 mA USB port. The step most people skip is cleaning the surface, which causes the strip to fall off.

What maintenance or replacement will the 20 LED strip need later?

The 20 LEDs are rated for long life, so no scheduled maintenance is required. If brightness drops below the 20–24 lm range or the colour temperature shifts from 5500–6000 K, replace the entire strip; no user-serviceable parts exist.

What limit appears first during sustained use of the 2.5 W strip?

The aluminium body dissipates the 2.5 W load, so thermal throttling is not an issue. The first practical limit is the 500 mA USB supply — if the port cannot maintain 5 V at 500 mA, brightness will fall below 20 lm.
