It's built for tile setters lighting a bathroom remodel, cabinet installers working in an unfinished basement, electricians tracing a run through a dark attic, or any tradesperson who's ever set up a job and realized the only outlet is on the other side of the room. This model replaces Festool item number 576411, the SYSLITE Duo-PLUS, and it's a real upgrade rather than a rebadge: the previous light was corded only, and this one adds true hybrid power that runs on an 18V battery or the included cord and switches between the two automatically.\u003c\/p\u003e\n\u003cp\u003eThe core spec that matters here is the light output: a 192-LED array delivers between 2,000 and 10,000 lumens, infinitely adjustable rather than locked to a fixed level — the outgoing 576411 topped out at a fixed 8,000 lumens with no dimming at all. At the low end, that's enough to work comfortably without glare bouncing off drywall in a small room. At the high end, it's enough to flood a garage bay or open floor plan with usable light. The 180-degree beam spread is what actually makes the lumen number useful — instead of one bright cone and dark edges, the light fills a wide arc, which is why Festool markets it for \"illuminating large work areas\" rather than spot lighting. Bluetooth connectivity and the Festool app are new to this model too, adding remote dimming, runtime tracking, and the ability to group multiple lights together — none of that existed on the light this one replaces.\u003c\/p\u003e\n\u003cp\u003eHybrid power is the other headline feature, and it's a genuine two-way system rather than a battery light with a cord as backup. Plug in the included 18 ft. (5.5m) plug-it cord and it runs indefinitely off wall power. Swap in a compatible 18V Festool battery pack and it goes cordless. The light automatically transitions between the two power sources as needed, so if a battery runs low while it's plugged in as backup, or a breaker trips, you're not left standing in the dark. Runtime on battery is 80 minutes at maximum brightness with a 5.0Ah pack, or 120 minutes with an 8.0Ah pack — plenty for a task light while you're moving a battery to a tool that actually needs it, or for filling in a temporary blackout.\u003c\/p\u003e\n\u003cp\u003eOn the jobsite-practicality side, Festool paid attention to the details that actually cause problems with work lights: loose cords and awkward placement. This model introduces a new cable-wrap handle with an integrated clamp, so the power cord winds around the carrying handle and clips into place instead of getting coiled separately or left to tangle underfoot. A new guide groove built into the handle lets you hang the light directly from a hook or a nail, which means you can mount it overhead for wide, shadow-free ceiling-style lighting instead of setting it on the floor where it throws long shadows across whatever you're working on. Rear mounting points also allow it to be screwed directly to a wall for a fixed installation. The housing carries an IP54 dust and splash rating and is built to shrug off the scratches and shock of daily jobsite use, and it includes temperature monitoring to protect the light during extended high-output runs.\u003c\/p\u003e\n\u003cp\u003eSystem compatibility runs through Festool's 18V battery platform — the SYSLITE DUO-H works with Festool 18V battery packs with the exception of the Ergo battery line, so most contractors already running Festool cordless tools can share batteries with this light instead of buying a dedicated one. It also mounts to the optional ST DUO 200 stand for elevated positioning up to 6.5 feet, useful for lighting a room from above rather than from the floor.\u003c\/p\u003e\n\u003cp\u003eBuy this if you need one light that covers a lot of ground, works whether or not there's power on site, and doesn't demand babysitting once it's set up. It's a strong fit for remodelers, electricians, plumbers, and drywall or paint crews working in unfinished or low-light spaces — basements, attics, crawlspaces, new construction before permanent lighting goes in. If your work is mostly small, focused tasks in already-lit rooms, a smaller battery-only work light will do the job for less money; the SYSLITE DUO-H earns its price on bigger spaces and longer days.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails id=\"product-whats-included\" class=\"acc\" open=\"\"\u003e\n\u003csummary\u003e\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003c\/summary\u003e\n\u003cdiv class=\"acc-body\"\u003e\n\u003cdiv class=\"tnincluded-wrapper\"\u003e\n\u003cul\u003e\n\u003cli\u003eFestool SYSLITE DUO-H Hybrid LED Work Light (1)\u003c\/li\u003e\n\u003cli\u003e18 ft.
