Festool 578511 Hybrid Work Light DUO-H I-Basic
– PRE ORDER – Available from OCTOBER 2026

Make the night into day, with battery or cable.
Say goodbye to dark corners: With its unique LED arrangement for a 180° scattering angle, the SYSLITE DUO-H hybrid work light illuminates your workspace brilliantly and over a wide area. If you prefer it less bright, the light can be dimmed seamlessly. No power supply nearby? No problem! The hybrid work light allows you to remain completely independent of local conditions. Use it flexibly with battery power or for extended periods using the supplied plug-it cable. The SYSLITE DUO-H offers even more: With the Festool app, you can control your work light intelligently – switching it on and off, dimming it, or checking the remaining runtime of your battery pack. Additionally, the group function enables you to control multiple work lights simultaneously.
Everything at a glance: 180° scattering angle for uniform room illumination.
