Streamlight MegaStream HP USB Flashlight

Streamlight, Inc. is launching the new MegaStream HP USB flashlight, the newest addition to the Stream series of handheld flashlights. The MegaStream HP USB is a high candela powerhouse, delivering 310,000 candela and a beam distance of 1,114 meters.

Engineered for professionals and everyday users alike, the MegaStream HP USB has three lighting modes, a push-button tail-cap switch with momentary or constant on operation and a USB-C rechargeable design, making it ideal for people who require far-reaching, bright illumination in a handheld, lightweight format.

The light provides 1,350 lumens on High, 470 lumens on Medium, and 145 lumens on Low, with run times of 2, 4 and 15 hours respectively. The MegaStream HP USB is powered by a 3,500mAh Streamlight SL-B34 lithium-ion battery pack with an onboard safety circuit. Charging is simple with a sliding sleeve that reveals the USB-C port, and an LED indicator shows charging status: red for charging, green for charged.

The MegaStream HP USB is the perfect blend of extreme performance and everyday portability,” said Michael F. Dineen, Streamlight president. “It delivers a powerful downrange beam, ideal for users who need serious light in a convenient, rechargeable package.”

The MegaStream HP USB is constructed from machined aluminum alloy with a Type II mil-spec anodized finish for abrasion resistance. It features an unbreakable glass lens, is IPX7 waterproof to 1 meter for 30 minutes, and is impact-resistance tested to 1 meter.

The MegaStream HP USB measures 6.61 inches in length, has a 1-inch body diameter and 2.24-inch head diameter and weighs 9 ounces with battery. It is available in black and ships with a USB-C cord, removable pocket clip and a holster. The light has an MSRP of $219 and more information on this light as well as other products made by Streamlight is available at streamlight.com.
