Most work light brands print logos on a box. DAYATECH backs every claim with paperwork you can verify.
Nine independent certifications. Third-party labs. Numbered reports. No marketing language — just the test data that qualifies these lights for electrical crews, utility contractors, and professional jobsites across North America and Europe.
This page lists every certification DAYATECH holds, what each one tests, and what it means when you specify a light for your team.
Issued by Intertek. Covers electrical safety for plug-connected and battery-powered luminaires sold in the US and Canada. A cETLus mark signals the product passed the same base standard as a UL listing — relevant for contractors on sites that require NRTL-listed equipment. Applies to: 363B, 368, 363Z, 363D.
↓ Download ETL / cETLus Certificate (PDF, 80 KB)ETL-Listed by Intertek. Confirms compliance with ANSI/UL 153 and CSA C22.2 No. 250 for luminaires. Verifies insulation, thermal cutoff, and short-circuit behavior under sustained load. Applies to: 363B, 368, 363Z, 363D.

DAYATECH lights pass FCC Part 15 Class B limits, meaning the driver electronics do not interfere with two-way radios, GPS receivers, or communication equipment on utility and construction sites. Applies to: all battery-platform variants.

Every DAYATECH SKU has a third-party LM-79 report on file documenting: total lumen output, CCT (color temperature), CRI (color rendering), beam angle, and efficacy (lm/W). When we say “4,000 lumens,” LM-79 is why that number means the same thing it would on a certified architectural fixture.
IES LM-80-08 tests LED chip lumen maintenance over 6,000+ hours at controlled temperature. DAYATECH LED packages hold LM-80 data supporting L70 estimates — the hours to 70% initial output. This is the standard data set used for DLC submissions and long-term fixture specification.
LM-80 chip-level test data is available by request for spec submittals — contact Support.
Volatile Organic Compound compliance covers the non-electrical portion of the product: enclosures, adhesives, lens materials. Relevant for indoor use, confined-space work, and facilities with air-quality restrictions.
↓ Download VOC Certificate (PDF, 323 KB)DAYATECH holds nine German utility patents covering the folding hinge geometry, the universal battery adapter architecture, the zoomable optical stack (363Z), and the thermal routing that lets a 7,000-lumen IP65 fixture (363D) run continuous without shutdown. These patents protect the original design work that made the DAYATECH foldable form factor possible. When competitors copy the shape, they copy what these patents describe.

If a light runs outdoors on a commercial jobsite, OSHA, the NEC, and many utility safety programs require electrically-listed fixtures. A crew lead pulling an unlisted fixture onto a switchyard can be cited — even if the fixture “looks fine.”
Certification matters downstream, too. If a project specifies “4,000 lumens minimum at the work plane,” an LM-79 report is what makes that spec verifiable. A box that just says “4,000 lm!!” is a guess.
DAYATECH built the certification stack first and designed the product second. Every number on the spec sheet traces back to a report we can send.
For procurement teams sourcing into the EU & UK, DAYATECH holds the full CE conformity package. Download any certificate below.
LM-79 fixture-level reports are published directly on this page — see the download links under each certification. For LM-80 chip-level data or sku-specific submittal packages, contact Support with the product model and we will email the full third-party lab report.
Both. The cETLus and FCC marks are printed directly on the fixture per NRTL listing requirements. Box labels carry the full certification set.
The adapter is tested as part of the integrated fixture under cETLus and ETL. The battery pack itself carries the original tool-brand (DeWalt, Milwaukee, Makita, Bosch) certifications.
The original DAYATECH design work was filed and granted under the German Gebrauchsmuster system, which protects functional designs. Equivalent US design-patent applications are part of the ongoing IP work.
