The Olight Seeker 4 is a high-performance flashlight delivering 3100 lumens with an impressive 40,260 candela beam intensity and a 400-meter throw. Powered by a 21700 5000mAh battery, it provides extended runtime for demanding outdoor activities, professional use, and emergency situations. The built-in proximity sensor is a critical safety feature that automatically reduces output when the bezel detects a nearby surface, preventing overheating in enclosed spaces or when the light is accidentally left on in a bag.
At 134mm long and 205 grams, the Seeker 4 occupies the sweet spot between compact EDC lights and full-size searchlights. The USB-C charging port provides fast, universal recharging from any modern charger or power bank, and the 21700 cell format offers the best energy density available in consumer flashlights. The IPX8 submersible rating ensures complete weather and water protection, so you can use this light confidently in any conditions — rain, snow, or even brief submersion.
The 400-meter throw combined with 3100 lumens means the Seeker 4 excels at both flood and distance tasks. Use it for search operations, trail navigation, property inspection, or outdoor recreation where you need serious illumination. The beam profile balances a bright central hotspot for distance with generous spill for peripheral awareness. At $109.99, it delivers flagship performance at a mid-range price point, making it one of the best values in the high-output flashlight category.
