The Keystone KT-CWLED44PS-4-8CSA-VDIM is a versatile 4-foot LED wrap fixture designed for commercial and industrial lighting applications including biotechnology laboratories requiring consistent color rendering and flexible illumination. Featuring Keystone Power Select technology, it offers adjustable wattages of 44W, 28W, and 18W with corresponding lumen outputs from 2,664 to 5,984 lumens and high efficacy ranging from 136 to 148 lm/W. The fixture supports Keystone Color Select technology, enabling selection among 3500K, 4000K, and 5000K color temperatures to optimize lighting for various research environments such as microscopy and cell imaging setups.
Powered by Keystone 0–10V dimmable LED drivers, this fixture allows dimming down to 10% brightness. Integration with the Smart Loop Bluetooth mesh wireless control system facilitates advanced lighting management including high-end trim, grouping, occupancy sensing, and scheduling—important for energy efficiency and controlled environments in biomedical and synthetic biology labs. It is also compatible with SmartSafe emergency backup systems to ensure uninterrupted illumination during power outages.
Constructed for durability and stable performance, the fixture boasts a long LED lifetime exceeding 100,000 hours (L70 at 25°C) with low optical flicker and a high power factor >0.95 to maintain electrical efficiency. Its operating temperature range from -20ºC to 45ºC supports installation in controlled storage spaces like clothes closets or specialized lab rooms. Keystone’s inclusion of an internal wireway and ½” NPS knockout on both ends simplifies end-to-end wiring continuity.
This LED wrap fixture is ideal for biotechnology labs, clinical diagnostics environments, and biopharmaceutical manufacturing areas where precise, adjustable lighting supports critical workflows such as fluorescence analysis, molecular diagnostics, and live-cell imaging. Its advanced power and color selection combined with robust dimming and wireless control features make it an essential component in modern bioprocessing facility lighting and research-grade laboratory setups.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
