Dual-White (CCT) LED Strip Lights

What are dual-white (CCT) LED strip lights? And what do they do?

Dual-white LED tapes, also known as CCT LEDs, are a great alternative for primary/task lighting and highlight installations that require white-light LEDs. Because their diodes are mounted in pairs, outputting two distinct shades of white light, dual-white LEDs enable you to adjust the tone of your lighting to suit your mood or the time of day.

Dual-white CCT stands for ‘correlated colour temperature’ LED tape. Elsewhere, you’ll find them referred to as tuneable white LEDs or adjustable white LEDs.

Just like other strip-light products, dual-white LED tapes can be manufactured to output different brightness levels (depending on the power they draw and the spacing between LEDs; more LEDs per metre gives better colour mix and less spotting). Use InStyle’s 12-watt strips for feature-lighting and highlights (around 1,250 lumens per metre when both whites are at full brightness), or our brighter 24-watt strips for task-lights and main room lighting ( ≈ 2,500 lumens per metre).

As we’ve discussed elsewhere, white light is typically measured on the Kelvin scale. The two white chips found in dual-white LEDs are rated 2700K (warm white, which has a yellow tint similar to traditional halogen bulbs) and 6500K (the opposite end of the scale, being a white with a slight blue tint).
