Adjustable 32-LED Macro Ring Light

Dimensions: 98 x 80 x 10 mm. Weight: ultra-portable design ideal for tabletop setups, travel kits or on-location jewellery shoots. Materials: impact-resistant ABS and PC outer shell with aluminium alloy structural frame for rigidity and thermal management. Power system: integrated 3.7V 200mAh rechargeable lithium battery, charged via USB-C (5V 1A), with full charge in ≤120 minutes. Light source: 32 high-efficiency SMD LEDs (16 warm, 16 cool), delivering consistent ≥2W optical output across 3500K–6200K range. Illuminance: 200–5000 lux measured at 5 cm—sufficient for close-focus macro work on rings, pendants and watch dials. Colour temperature accuracy: ±200K tolerance around 3500K, 4400K and 6200K presets. CRI: ≥95 at 3200K and 5600K—verified for accurate reproduction of metallic sheen and gem refraction. Control: four-level brightness (20%–100%) and nine lighting configurations (full/warm-only/cool-only + left/right half combinations). Mounting interface: M52 male thread on light body, supplied with 37–52 mm step ring for seamless fit on most smartphone lens attachments. Safety certified: CE, RoHS, UN38.3 (battery transport), and MSDS compliant. Thermal performance: surface temperature rise limited to ≤25°C after 3 hours continuous operation at room temperature.
