The GLI 18V-10000 C Professional from Bosch is worldwide the brightest cordless floodlight with 18 volts and connectivity. Its LED, with a luminous flux of 10,000 lumen, is about five times brighter than the most powerful Bosch floodlight up to now, the GLI 18V-2200 C Professional. The brightness level surpasses that of a common 500 watts halogen floodlight and efficiently lights up even large work areas, rooms or halls. A further advantage is the long runtime: At a medium brightness level, the floodlight with the high-performance battery ProCore18V 12.0 Ah provides light for around six hours. At maximum brightness, it effortlessly bridges particularly dark morning or evening hours. Furthermore, the floodlight is very robust: A shock-absorbing frame surrounds the metal housing with integrated cooling ribs. In addition, safety bars protect the LED element against damage.

Fingertip control ‒ Connectivity function for more ease of use

Tradespeople can connect the cordless floodlight with their smartphone via Bluetooth and use the app for convenient remote control: Switching on and off, dimming, coupling with several floodlights from the Connectivity program from Bosch, activating timers, checking the charging state of the battery, controlling access via PIN code – all this can be done at a fingertip. Bosch continuously expands its Connectivity system for professionals.

Versatile and flexible usage

Thanks to its three brightness levels, the GLI 18V-10000 C Professional can be adapted to the respective lighting conditions – the selected level is always displayed. Tradespeople have the remaining battery runtime always in sight thanks to a five-stage charging display. The 5/8” thread ensures high flexibility in every work situation: The floodlight is thus simply screwed onto a tripod ‒ for example, the BT 300 HD Professional from Bosch ‒ and can be positioned wherever you like.

If less brightness is sufficient, tradespeople can rely on the GLI 18V-4000 C Professional. It offers the same advantages as the GLI 18V-10000 C Professional with regard to robustness and connectivity, and lights up work areas with up to 4,000 lumen. 

Fully compatible with the existing 18 volt range

GLI 18V-10000 C Professional and GLI 18V-4000 C Professional are operated by powerful 18-volt lithium-ion batteries. Regardless of which battery you use, the Bosch Professional 18-volt system guarantees compatibility with new and existing power tools and chargers in this voltage class. The longest runtime is provided by the high-performance battery ProCore18V with 12.0 Ah. 

The cordless floodlights GLI 18V-10000 C Professional and GLI 18V-4000 C Professional are available from January 2020 onwards. The prices are the recommended retail prices excluding VAT.
