The Festool 578055 LM-OF 1010 R Light Module is a retrofit LED light module for the Festool OF 1010 R router. This is a router light module designed for improving visibility during precision routing. Model Number 578055 gives OF 1010 R users a cleaner view of the cutter and layout line, which matters most when you're following scribe marks, cutting script, or working in dim corners of a shop or jobsite.

The main advantage here is simple: better visibility leads to better routing. Festool built the LED light ring to sit directly in the router base, where it throws shadow-free light around the bit and onto the workpiece. That all-around lighting helps you stay on your mark instead of guessing around shadows from the motor housing or your hands. If you do trim work, template routing, or fine edge detail, that extra visibility is not a gimmick. It directly helps accuracy.

Festool also handled the power setup the right way. The separate battery unit is removable, so you can charge it independently through a USB-C port instead of tying up the whole router. That is a practical setup for real use because the light ring can remain installed in the machine, and the battery unit can be recharged as needed. Runtime is rated for up to six hours, which is plenty for detailed routing sessions, punch-list work, or a day of intermittent use.

The system gives you two selectable brightness levels, so you can adjust the output to the work area instead of blasting more light than you need. In a bright shop, one level may be enough. In tighter cabinetry, under-install work, or low-light site conditions, the higher setting gives you a clearer look at the cut path. That flexibility makes the module more useful than a fixed-output add-on.

From a design standpoint, this is the kind of accessory that fits the Festool approach well. It is meant to be a one-time retrofit rather than a temporary clamp-on light. Once installed, the ring stays integrated in the router base, keeping the setup clean and close to the cutting area. Because the light source is positioned near the workpiece, it does a better job of reducing shadows where you actually need to see.

Compatibility matters here. This light module is intended for retrofitting the Festool OF 1010 R from production month 09/2021. If you already own that router and want better visibility without changing the tool's footprint much, this accessory makes sense. If you do not have the compatible router generation, this is not a universal router light and should be matched carefully before purchase.

This is best suited for woodworkers, finish carpenters, cabinet installers, and serious DIY users who already rely on the OF 1010 R for accurate routing. If your work depends on seeing a line clearly and keeping the bit exactly where it belongs, the Festool 578055 LM-OF 1010 R Light Module solves a real problem. It will matter less to users doing rough routing in full daylight, and a lot more to anyone doing detailed cuts where visibility makes or breaks the result.
