01. Light Quality
The Spectrum of White
Correlated Colour Temperature (CCT) defines the exact chromaticity of white light, measured in Kelvin (K). It orchestrates the entire psychological impact of a space.
Use 2700K for high-end hospitality environments to induce deep relaxation. Use 4000K in sterile medical or focused corporate spaces to suppress melatonin and drive visual acuity.
CCT Thermal Scale
Color Fidelity Index
High-Definition Reality
Colour Rendering Index (CRI) measures the precision with which light reveals the true colours of illuminated objects. It dictates the material perception in a space.
A low CRI renders premium surfaces (marble, rich timber, luxury textiles) as cheap and muted. CRI 90+ is the undisputed baseline for architectural lighting.
Binning Consistency
Standard Deviation Color Matching (SDCM) tracks the microscopic variance between individual LED nodes using MacAdam ellipses. It guarantees uniform color down long continuous linear runs.
The human eye cannot accurately distinguish color shifts beneath a 3-step MacAdam ellipse. Architape guarantees 3-step precision to prevent 'patchy' lines of light.
02. Performance
The Luminous Engine
Efficacy (lm/W) is the apex metric of engineering efficiency. It mathematically dictates how much brilliant light is generated per single watt of electrical payload.
Low-efficacy tapes waste power as heat rather than light, drastically shortening LED lifespan. Architape Platinum strikes 140+ lm/W for massive output with virtually no thermal stress.
Efficiency Benchmarks (lm/W)
Photometric Precision
The photometric angle controls atmospheric deployment. A wide 120° beam paints walls in uniform washes of light, while narrow optic profiles (15° - 60°) graze textures or accent specific geometries without light spill.
03. Engineering
Electrical Architecture
Wattage (W/m) forces the physical footprint of remote drivers controllers. Specifying high-wattage arrays without required photometrics recklessly inflates electrical infrastructure costs.
Watts = Volts × Amps. An over-specified 25W/m tape deployed over a 50m corridor will require massive 1.2kW power supplies and oversized cables.
Power Density Curve
Voltage Drop Topology
Hydraulic Tension
Lower voltages (12V) succumb to severe 'Voltage Drop' over distance, causing the far end of the tape to visibly dim and color-shift. Architecturally demanding spaces utilize 24V or pure 48V topology.
Architape's 48V Constant Current integration guarantees entirely stable luminosity across uninterrupted runs exceeding 30 metres from a single electrical feed.
04. Physical
Sub-Millimeter Profiles
Physical geometries dictate integration feasibility. A 12mm wide PCB tape will never fit inside a 10mm microscopic joinery extrusion. Always verify component cross-sections prior to routing tracks.
Modular Topology
Granular Boundaries
Cutting topology sets the smallest modular unit of an LED run. A micro-step (25mm) ensures pure, shadow-free illumination edge-to-edge in wall recesses. Long 100mm steps risk leaving dark voids at the end of runs.
05. Reliability
Lumen Degradation
LEDs do not "burn out" like halogens; they slowly dim forever. L70 quantifies the exact hour count at which luminosity universally depreciates to an unacceptable 70% of day-one output.
Architape's "60,000 Hours (L70 B10)" explicitly guarantees that at the 60,000-hour mark, only 10% of the diodes will have degraded past the 70% brightness threshold. This is industrial-grade longevity.
Lumen Depreciation Graph
Environmental Armor
IP classifications shield electronics against total systemic failure. The first integer blocks physical ingress (dust/solids); the second seals against hydrodynamic pressure (condensation/immersion).
BEYOND THE
DATASHEET.
Engineering elite lighting requires more than blindly meeting a specification. It demands an absolute mathematical understanding of how these metrics combine to execute architectural intent.
