Fundamental Photometric and Electrical Concepts

Lumens (Lumens, lm) The standard unit for quantifying the total visible light output from an LED source, essentially measuring “brightness.” Higher lumen values deliver superior illumination under equivalent power consumption, promoting energy efficiency. When selecting high-brightness flexible LED strips for living room accent lighting, prioritize lumen ratings—our products exceed 150lm/W for maximum efficacy.
Correlated Color Temperature (CCT / Correlated Color Temperature) Expressed in Kelvin (K), this metric delineates the hue of white light from warm to cool tones. Low CCT (2200K-3000K) yields cozy amber glows ideal for bedrooms; neutral CCT (4000K-5000K) mimics daylight for workspaces; high CCT (6000K-6500K) provides crisp, invigorating illumination. NPHIS tunable CCT flexible LED strips for kitchen under-cabinet lighting enable seamless adjustments to suit diverse environments.
Color Rendering Index (CRI / Color Rendering Index) A scale from 0-100 assessing a light source’s ability to accurately reproduce colors relative to natural sunlight. Values ≥80 suffice for general applications, while ≥90 is essential for color-critical settings like galleries or retail. Our high-CRI COB LED strips for jewelry display cabinet illumination achieve 95+ CRI, ensuring vibrant, lifelike color fidelity.
Alternating Current (AC / Alternating Current) and Direct Current (DC / Direct Current) AC represents the standard grid-supplied power (e.g., 110V-240V) with oscillating direction; DC is the stable, unidirectional low-voltage current (e.g., 12V/24V) preferred for LEDs due to safety and efficiency. Transformers are required for conversion. All NPHIS waterproof rigid LED bars for outdoor landscape lighting include compatible AC-DC drivers for universal voltage compatibility.
Watts (Watts, W) The unit denoting electrical power consumption, computed as voltage multiplied by current. Opting for low-wattage, high-lumen options enhances sustainability. For instance, our low-power neon LED strips for commercial signage illumination operate at just 5W/m while rivaling traditional neon brightness, reducing operational costs.
Voltage (Voltage, V) The measure of electrical potential difference, with common LED variants at DC 5V, 12V, or 24V. Higher voltages like 24V minimize drop-off in extended runs. NPHIS 24V flexible LED strips for large-scale architectural contour lighting support up to 50m continuous operation without degradation.
Current (Current, A or mA) The rate of charge flow, typically in amperes (A) or milliamperes (mA). Constant current designs safeguard LEDs from fluctuations. Our constant-current COB LED strips for hotel lobby linear lighting maintain stable flow, extending lifespan beyond 50,000 hours.

LED Chip Type Comparisons

2835 LED Chip A compact 2.8mm × 3.5mm chip renowned for high brightness, excellent thermal stability, and cost-effectiveness. Ideal for moderate-power scenarios to prevent overheating. Featured in our everyday residential flexible LED strips and LED backlit strips for supermarket poster illumination.
5050 LED Chip A 5mm × 5mm tri-color RGB-integrated chip offering rich color saturation and superior mixing. Perfect for dynamic applications. NPHIS 5050 RGB LED strips for stage lighting effects deliver over 16 million color variations.
3528 LED Chip A 3.5mm × 2.8mm miniature chip with low power draw and subdued brightness, suited for supplementary or ambient lighting. Our low-intensity 3528 flexible LED strips for bedroom mood lighting emphasize energy conservation.
5630 LED Chip A 5.6mm × 3.0mm high-output chip capable of 50lm per unit, tailored for intensive illumination needs. Utilized in NPHIS high-power rigid LED bars for industrial warehouse lighting.
COB (Chip on Board) Chip Multiple chips directly bonded to a substrate for dot-free, uniform luminescence with soft, glare-reduced output. Optimal for linear setups, as in our dotless COB LED strips for storefront window display lighting.
SMD (Surface Mounted Device) Surface-mount technology where chips are affixed directly to PCBs for efficient mass production. Virtually all NPHIS strips employ SMD for enhanced reliability.

Protection and Durability Terms

IP Protection Rating (Ingress Protection Rating) An international code with the first digit (0-6) for dust resistance and the second (0-9) for water ingress. IP20 for indoor dust protection; IP65 for jet resistance; IP67 for temporary submersion; IP68 for prolonged immersion. For exterior applications, choose our IP68 waterproof neon LED strips for pool edge illumination or IP67 flexible LED strips for garden pathway lighting.
Lumen Depreciation (Lumen Depreciation / Lumen Maintenance) The percentage decline in LED brightness over time. Premium products exhibit <20% depreciation after 30,000 hours. NPHIS durable rigid LED bars for retail shelf lighting limit depreciation to under 10%.
Junction Temperature (Junction Temperature) The internal chip temperature; excessive levels accelerate failure. Effective dissipation keeps it below 80°C. Our aluminum-substrate heat-dissipating COB LED strips for high-temperature environment lighting optimize thermal management.
Lifespan Estimate (Lifespan / Rated Life) Projected operational hours, often as L70 (time to 70% lumen retention). NPHIS products average 50,000-100,000 hours.

Installation and Accessory Terms
