The ZHIYU BL-W51 COB LED Work Light packs 800 lumens of bright, wide-angle illumination into a compact, foldable body — all rechargeable via USB so you're never caught in the dark without power. Key Features 5 Versatile Lighting Modes: High COB, Low COB, Front LED, Steady Red Warning, and Flashing Red — switch modes easily with a long-press for red light modes. 360° Rotary Design: Rotate the head a full 360° for multi-angle illumination, making it ideal for tight spaces under the hood or in confined work areas. USB Rechargeable & Long Runtime: Built-in 1200mAh 18650 lithium battery charges fully in ~3 hours via any USB source (power bank, laptop, car charger, AC adapter). Delivers 3–6 hours on High mode and an impressive 10–16 hours on Low mode. Super-Strong Magnetic Base & Hanging Hook: The powerful magnetic bottom sticks firmly to any metal surface, keeping the light exactly where you need it hands-free. The built-in hook lets you hang it overhead for wide area coverage. Durable & Portable Build: Hard rubber body offers a secure, non-slip grip; aluminum head effectively dissipates heat to extend lamp life. Folds flat to slip into a shirt or pants pocket with ease. Water-Resistant Design: Handles rain and snow conditions confidently — great for roadside emergencies, outdoor work, and camping. (Note: Do not submerge in water.) 180° Wide Beam Angle: COB LED strip delivers broad, even light coverage — no dark spots or hot zones.

Frequently Asked Questions Q: How do I switch to the red warning light mode on the COB LED work light? A: To activate the red light modes, long-press the switch button. This toggles between the steady red warning light and the flashing red light — both great for roadside emergencies or attracting attention in low-visibility situations. Q: Can I use this COB work light while it is charging via USB? A: While it is generally best to fully charge the built-in 1200mAh lithium battery before use, the USB recharging port is compatible with a wide variety of sources including laptops, power banks, car chargers, and AC adapters — making top-ups convenient no matter where you are. Q: Is the magnetic base strong enough to hold the light under a car hood? A: Yes! The upgraded super-strong magnetic base is designed to firmly grip metal and steel surfaces, including under vehicle hoods and inside machinery panels, keeping the light securely in position while you work hands-free. Q: What is the difference between the Big and Small models? A: The Big model measures 14.8 × 4.7 cm and offers a larger grip and potentially brighter output for heavy-duty tasks, while the Small model at 11 × 3.6 cm is ultra-compact for tight spaces and pocket carry. Both share the same 5 lighting modes and USB rechargeability. {"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "How do I switch to the red warning light mode on the COB LED work light?", "acceptedAnswer": {"@type": "Answer", "text": "To activate the red light modes, long-press the switch button.
