microphones (typically 6 to 12) positioned in a hemispherical or cuboidal configuration around the device under test. The chamber is also equipped with vibration iso- lation and background noise con- trols to ensure accuracy.
Measurement Results The certified results for the
new Guard series:
l ZeroSmog Guard Light: 44.1 dBA l ZeroSmog Guard: 47.9 dBA l ZeroSmog Guard 2: 52.7 dBA
Practices NORTH ATTLEBOROUGH, MA — As lighting manufacturers respond to rising sustainability standards and demand for envi- ronmentally responsible products, DISTRON is leading by example. The U.S.-based contract manufac- turer has implemented a series of sustainability-driven practices specifically tailored for the design and assembly of LED lighting products and controls. For more than 55 years,
DISTRON has supported OEMs across the industrial, clean tech, medical, and defense sectors. Today, it brings that same man- ufacturing rigor to a new priori- ty: energy efficiency and environ- mental responsibility in PCB assembly and full box-build serv- ices for lighting OEMs. DISTRON’s sustainability
strategy is built on three core pil- lars: materials
compliance,
resource efficiency, and waste reduction. By aligning with evolving global regulations and customer expectations, DIS- TRON helps lighting manufac- turers not only comply with requirements, but also reduce the total environmental footprint of their supply chain. Lighting systems — particu-
larly those deployed in medical, industrial, or harsh environ- ments — require strict perform- ance and quality assurance. DIS- TRON supports these needs with in-house testing, robust process documentation, and complete lifecycle traceability. Its vertical- ly integrated services extend from PCB assembly and cable harnessing to mechanical inte- gration and functional testing. Contact: DISTRON Corp.,

DISTRON Integrates Sustainable
l 44 dBA is comparable to a quiet library. l 48 dBA is similar to light rainfall. l 53 dBA resembles a quiet con- versation at home.
Competitor Comparison l Competitor A: 61.1 dBA l Competitor B: 58.5 dBA
To match the sound level of
one Competitor A unit (61.1 dBA), you could run nearly 5 Guard 2 units simultaneously: 52.7 + 10 log10(5) ? 52.7 + 7 = 59.7
dBA, still quieter than a single Competitor A.
This demonstrates the effi-
ciency of Weller’s design — lower sound means more units can be used without dramatically increasing background noise. Accessories like hoses,
extraction arms, shut-off valves, and funnels can increase the per- ceived noise by introducing tur- bulence or amplifying vibrations. Proper selection, such as flexible, sound-dampening hoses and aerodynamic nozzles, can signifi- cantly reduce this effect. Noise is not just a comfort
factor: it’s a performance differ- entiator in the design of fume extractors. Weller’s new Guard line not only meets international safety and performance stan- dards but sets new benchmarks in acoustic comfort. In work- spaces where every decibel counts, choosing quieter equip- ment improves health, communi- cation, and productivity. Contact: Weller Tools
