Don't settle for copycats. DAYATECH holds the first patent for the universal battery-compatible work-light design — registered and protected in Germany.
DAYATECH filed the first patent for the universal battery-compatible work light — in Germany. Every copycat came after us. Here's the proof: German Utility Patent Gebrauchsmuster Nr. 20 2019 100 940.
We Don't Guess. We Test.
Every performance number comes from an independent LM-79 laboratory — the gold standard for LED measurement.
LM-79 Tested — Every Product in the Line
Numbers below come from the finished product, at operating temperature, measured in an independent integrating sphere. Not chip ratings. Not estimated. Not marketing.
What Is LM-79?
LM-79 is the ANSI/IES standard for measuring complete LED products in an independent lab. It tests the actual finished light at operating temperature — not raw chip specs.
Why Real Lumens Matter
Most brands quote LED chip ratings that can be 20–50% higher than what the light actually delivers. LM-79 measures what reaches your work surface — not what's on the spec sheet.
Four Technologies. One Certified Promise.
UniPower™ universal battery compatibility · VoltShield™ low-voltage protection · TrueBeam™ zero-flicker engine · SteadyLume™ lumen maintenance. Four engineered systems, every unit, every certification.
UniPower™ Universal Battery
UniPower™ accepts 18V–20V MAX lithium-ion batteries from the four top pro brands: DeWalt, Milwaukee, Makita, Bosch. No adapters. No power loss. No compatibility warnings. The only work light that works with the batteries you already own.
VoltShield™ Low-Voltage Protection
VoltShield™ watches battery voltage in real time. When it drops too low, the light shuts off automatically. This prevents over-discharge, which kills lithium-ion cells for good — saving your $50–80 battery every time.
TrueBeam™ Zero-Flicker Engine
TrueBeam™ uses a constant-current LED driver to remove the invisible flicker you get in most work lights. No eye strain, no headaches, no fatigue on long shifts — which matters when you're doing detail work: electrical, mechanical, or inspection.
SteadyLume™ Lumen Maintenance
SteadyLume™ manages heat so LED chip temperatures stay low. That keeps lumen output steady from start to finish. Most competing lights lose 30–50% brightness in the first hour — DAYATECH holds rated output all the way to empty.
UniPower™ — One Light, Any Battery.
The average pro owns $500+ in batteries across the four premium platforms. DAYATECH is the only work light that runs on DeWalt, Milwaukee, Makita, and Bosch — no adapters, no compromises.
