Quick Answer
LED strip beam angle determines light distribution: 120° standard for directional task/accent lighting; 180° wide-angle (COB) for even cove/channel illumination; 360° round neon flex for all-direction glow ideal for signage and decorative applications. Choose based on how light is viewed and desired effect.
What is Beam Angle?
Beam angle describes the angular spread of light emitted by an LED, measured as the angle where intensity drops to 50% of maximum (half-power points). Narrower angle concentrates light, wider angle spreads it broadly. Affects appearance, reach, and uniformity of illumination.
120 Degree Beam Angle (Standard SMD)
Most common for standard SMD strips (2835, 5050, 5730). Directional light output. Good for: task lighting, accent lighting, cove lighting directed at specific surface, backlighting. Advantages: higher peak brightness, longer throw. Disadvantages: hot spots at close range, less uniform on nearby surfaces.
180 Degree Beam Angle (Wide/COB)
Very wide, even light distribution across hemisphere. COB strips typically 180°. Good for: cove lighting (indirect/reflected), linear fixtures, aluminum channels, uniform illumination without hot spots, light boxes. Advantages: very uniform shadow-free, no hot spots, ideal for indirect lighting. Disadvantages: lower peak brightness, shorter throw.
360 Degree Beam Angle (Round Neon Flex)
Light emitted in all directions (full circle), typical of round LED neon flex. Creates glowing tube effect like traditional glass neon. Good for: channel letters/signage (multi-angle viewing), hanging signs, decorative lighting, architectural outlines, railing lighting. Advantages: uniform glow all angles, no dark side, premium neon appearance. Disadvantages: less efficient for directional lighting, may need mounting clips.
Choosing the Right Beam Angle
Consider: 1) How strip is viewed (visible = 180+/360, hidden = 120). 2) What is illuminated (task = 120, indirect cove = 180, visible glow = 360). 3) Distance to surface (close = 180 for even, long = 120 for reach). 4) Use of diffusers (less critical with diffusers). 5) Brightness needs (max brightness = 120, uniform glow = 180+).

Frequently Asked Questions
Q: Are s-shaped neon mounting channel dimmable?
A: Yes, s-shaped neon mounting channel support multiple dimming methods including 0-10V, PWM, TRIAC, DALI, and DMX512 when used with compatible dimmers and drivers. COB strips dim especially smoothly due to their uniform light output.
Q: Do you offer OEM/ODM services for s-shaped neon mounting channel?
A: Yes, Arraystar LED provides comprehensive OEM/ODM services including custom PCB design, specific LED binning, custom color temperatures, private labeling, and custom packaging. Our factory has 15+ years of experience serving clients in 80+ countries.
Q: What is the lifespan of s-shaped neon mounting channel?
A: Quality s-shaped neon mounting channel from Arraystar LED have a rated lifespan of 50,000+ hours (L70). Actual lifespan depends on operating temperature, current drive, and environmental conditions. We offer 3-year warranty on all products.
Q: What power supply do I need for s-shaped neon mounting channel?
A: Choose a power supply matching your strip's voltage (12V/24V/48V) with wattage at least 20% higher than total strip consumption. For example, a 5m 14.4W/m strip needs at least 72W + 20% = 86.4W, so a 100W power supply is recommended.
Q: Can s-shaped neon mounting channel be cut to custom lengths?
A: Yes, most s-shaped neon mounting channel can be cut at designated cut points (typically every 5cm or 10cm depending on LED density). Always cut at the marked copper pads and use proper connectors or soldering for reliable connections. COB strips offer mini-cut options with 2.5mm intervals.
