The LED Smart Light Panel brings a new level of control and convenience to interior grid ceiling applications. Equipped with an on-board sensor that supports both occupancy sensing and daylight harvesting, this LED luminaire is the ultimate energy reduction tool. And while this functionality comes standard out of the box, it can be fully customized with just a few taps to your mobile device. Our new mobile app, LiteSmart, enables fixtures in a space to be grouped together and function as one; they can be turned on/off, dimmed, or programmed based on your schedule. Settings can be adjusted and pushed live in seconds. Custom scene configurations can also be created to meet the various needs of the space. Installation is simple and quick; this LED panel upgrade fits seemlessly into all standard 2’ x 4’, 2’ x 2’ or 1’ x 4’ grid ceiling layouts. Once installation is complete, all functionality can be set up via LiteSmart, then controlled through the app or a wireless remote switch. The LED Smart Light Panel delivers up to 125 lumens per watt (LPW) over the course of it’s 100,000-hour rated life. It ensures long-term energy savings over traditional fluorescent bulbs and ballasts, as well as eliminates routine maintenance, making it perfect for updating existing grid layouts or implementing in new construction. Furthermore, it’s backed by an industry-leading 10-year warranty, guaranteeing peace of mind for the life of your fixture.

Cleanrooms, controlled environment and containment spaces are used in a number of applications for industries such as medical, food processing, electronics, pharmaceuticals, biology and aerospace. Standards for cleanliness in these rooms have been published previously in FS209E and ISO 14644-1. These standards apply to air-flow, surfaces and other processes integral to maintaining very low particulates. Light fixtures in cleanrooms must be sealed to prevent the accumulation of particulates inside the housing that may then lead to the contamination of the facilities sealed air-flow. Cleanrooms frequently require different levels of light based on the types of activities taking place. The KURTZON™ EL-FG-2x2LP-LEDFE is a recessed high lumen fixture with replaceable LED arrays using commercially available COB arrays warranted for 5 years. Available in 4000K and 5000K CCT, with 70 or 80 CRI, highly consistent color maintained to 4 SDMC. The housing is a one piece, robotically seam welded unit with hole free 20-gauge CRS construction with integral heat sink. The inset door frame is made from welded channels that regress into the housing to allow the neoprene gasket to seal to the housing, and the door frame is hinged by aircraft cables and secures to housing with captive stainless-steel pan head screws. The fixture is IP55 rated for dust and water ingress, ETL listed per UL_1598 for wet locations and Chicago Plenum Rated.

LED - Cleanroom 4” Downlight Luminaire Certolux CRD4 Cleanroom Downlight offers sealed, IP-rated LED lighting ideal for sterile environments and controlled spaces. CRD-4 When precision lighting matters most, the Certolux CRD-4 (4-inch) Cleanroom Downlight delivers unmatched performance with dimming capabilities down to 1%. Engineered for environments where contamination control is critical, this luminaire is ideal for cleanrooms rated ISO 3–9 and BSL 1–3. Its sealed optical assembly and flush lens design ensure a smooth, cleanable surface that supports sterile conditions, making it a top choice for labs, pharmaceutical facilities, and controlled environments. Designed specifically for cleanroom lighting applications, the CRD-4 integrates a factory-sealed COB LED engine that’s field-replaceable and serviceable from below. It offers a wide range of color temperatures (2700K–5000K) and CRI options up to 97+, including high R9 values for enhanced color rendering, critical for tasks requiring visual accuracy. The luminaire supports full-range dimming to 1% via a 0–10V protocol, with optional DALI drivers available. Its high efficacy (up to 97 lm/W) and long lifespan (L70 > 60,000 hrs) ensure reliable, energy-efficient performance. What sets the CRD-4 apart is its antimicrobial finished trims, available in gloss or matte white polyester powder coating. These finishes help inhibit microbial growth, supporting hygiene protocols in sensitive environments. The trim is secured with EPDM closed-cell gaskets that seal the lens and reflector, preventing air leakage and contamination. Installation is flexible, with compatibility for grid, drywall, and cleanroom panel ceilings up to 2.5” thick. The adjustable plaster ring allows for vertical alignment post-installation, simplifying set

EarthBulb direct wire LED linear T8 lamps eliminate the need for electronic ballast or drivers for maximum energy savings. This 4000K color temperature lamp consumes only 15 watts to produce 2200 lumens. A high Color Rendering Index (CRI) of 82 insures excellent color clarity. The 300 degree beam angle provides a wide distribution pattern and is perfect for directing more light to the working surface from existing troffer fixtures and strip fixtures as well as task and display lighting applications. Perfect for replacement of T8 fluorescent tubes. To install, simply remove the existing fluorescent ballast and direct wire to the line voltage. This type B lamp is direct wire so no lamp holder modifications are necessary, just run the black (load) to the one end of the lamp and white (neutral) to the other. DLC® Listed.
