"Designed for the architect, interior designer and lighting consultant who needs a strip that performs exactly as specified — no brightness drop, no hotspots, no guesswork. The 2835 24V range is built for cove lighting in five-star hotels, joinery integration in luxury residences, and linear architectural elements in commercial flagship spaces."

The 2835 SMD Chip — Why It Matters for Specification

The SMD 2835 is the workhorse of architectural-grade LED strip lighting. At 2.8 × 3.5mm, it delivers a higher lumen-per-watt efficiency than the smaller 2016 chip while remaining compact enough to achieve 480 LED per metre densities on multi-line configurations. Paired with 24V constant voltage — the professional standard for linear runs — the result is consistent colour temperature, predictable brightness and the run lengths that commercial projects demand. Every strip in this range delivers 24–26 lumens per LED at CRI 80+.

Choosing PCB Width — Matching Strip to Profile

PCB width determines which LED aluminium profile channel the strip will fit, and how far the diffuser sits from the LED surface. Specify width before selecting density or wattage:

3mm
Coin-edge profiles, ultra-narrow slots
5mm
Most recessed & surface profiles
8mm
Medium surface & corner profiles
10mm
Standard cove & wide recessed
15mm
2-line — feature walls, open coves
20mm
3-line — maximum surface brightness

LED Density — Selecting for Uniformity

Higher LED density reduces point spacing, eliminating visible hotspots in diffused outputs. Match density to viewing distance and diffuser depth:

60 LED/m
5W–6W/m
Indirect coves viewed at distance. Deep diffuser channels. Low ambient wash.
120 LED/m
5W–12W/m
Standard cove lighting. Most profile systems. Good uniformity through 10mm+ diffuser depth.
168–180 LED/m
12W–15W/m
Joinery lighting. Mirror surrounds. Tight diffuser channels. High output coves.
240 LED/m
11W–22W/m
Under-shelf display. Premium joinery. Spotless uniformity. E Series high-output option.
360–480 LED/m
23W–26W/m
Multi-line strips. Feature walls. Open-face channels. Maximum surface brightness.

Dropless 20 Metre Roll — No Injection Points

The 10mm 120 LED/m option is available as a Dropless 20 Metre Roll — engineered to maintain consistent brightness across the full 20m length from a single 24V feed. Standard strips require power injection every 5–10m, creating interruptions in long continuous coves. The Dropless roll eliminates this entirely — one driver, one clean run, zero visible brightness variation end to end. Specified for long hotel corridor coves, retail perimeter lighting and large commercial linear applications.

Colour Temperature Range

From human centric 2700K to clinical 6500K — matched to the project's lighting design intent:

2700K
Extra Warm
Luxury / Residential
3000K
Warm White
Hospitality / F&B
3500K

Tunable White & RGBCCT: Multiple strips in this range support dual-channel tunable white (CCT shift from warm to cool) or full RGBCCT (colour + tunable white from one strip). These are specified for human centric lighting applications — hotel rooms, healthcare, premium offices — where colour temperature changes through the day are part of the design brief.

Technical Questions

Why specify 24V over 12V for architectural LED strip installations?
24V allows continuous runs up to 10 metres per channel without voltage drop causing visible brightness variation — compared to approximately 5 metres on 12V. For long coves, perimeter runs and corridor lighting in commercial and hospitality projects, 24V is the professional specification standard. It also reduces current draw, allowing smaller wiring gauge and driver specifications.
How do I choose the right LED density for a project?
LED density determines dot visibility and light uniformity. For applications viewed at close range or through narrow-aperture profiles — under-shelf, joinery, mirror surrounds — specify 180–480 LED/m to eliminate hotspots. For recessed coves viewed indirectly at a distance, 120 LED/m through a 15mm+ diffuser channel often provides excellent uniformity. Always match density to the diffuser channel depth: deeper channels are more forgiving of lower densities.
What is the E Series and when should it be specified?
E Series variants offer higher LED density and wattage on a given PCB width. On 8mm PCB, E Series delivers 12W/m or 15W/m versus the standard 5–10W/m. On 10mm, E Series reaches 22W/m at 240 LED/m. Specify E Series when the design requires maximum lumen output from a specific profile width — for example, a 10mm recessed slot that must deliver the brightness of a much wider strip.
What does 'Dropless 20 Metre Roll' mean?
Standard strips require power injection every 5–10m to prevent visible brightness drop. The Dropless 20m Roll maintains consistent brightness across its full 20m length from a single 24V feed — no injection points, no interruptions in long continuous installations. Ideal for hotel corridor coves, retail perimeters and large linear architectural runs.
What PCB width fits which LED aluminium profile?
3mm fits ultra-narrow coin-edge profiles. 5mm suits the majority of standard recessed and surface profiles. 8mm fits medium surface and corner profiles. 10mm fits standard wide recessed cove channels — the most common hospitality specification. 15mm and 20mm multi-line strips are for open-face channels where maximum surface brightness is needed without a diffuser, typically feature walls and display backlighting panels.
What colour temperature options are available?
Single white: 6500K, 5000K, 4000K, 3500K, 3000K and 2700K. Tunable white (dual-channel CCT) allows dynamic shift between warm and cool white. RGBCCT combines five channels (Red, Green, Blue, Cool White, Warm White) for full colour plus tunable white — the most versatile option for hospitality mood lighting and human centric lighting systems.
