Overview

This dimmable LED magnetic strip retrofit kit is designed to replace the ballast and tubes in 2' x 2' fluorescent troffers. Bright and powerful—the 40-watt LED retrofit kit emits up to 5200 lumens of warm, natural, or cool white light—equivalent to the output of 4 17-watt fluorescent T8 tubes. They're designed to last 5 times longer than fluorescent lights. The LED lights have magnets every 5” for secure mounting, and they operate on 100-277 VAC. A 0-10V dimmable constant-current driver is included, and brightness can be controlled with a 0-10V dimmer. This LED magnetic retrofit kit is perfect for homes, offices, schools, hospitals, and more!

Dimming Type TRIAC Dimming: Triode for alternating current (TRIAC) dimming is used to control high-voltage dimmable power supplies such as Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers, which include brand names such as Lutron and Leviton. Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies such as Mean Well HLG Series and Mean Well LPF Series. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer. Pulse-width modulation for these drivers is based on a 10V signal level with a frequency between 100Hz~3KHz. The MCBRF-4A or MLD-5A are compatible for this application. Resistive Dimming: Resistive dimming can be used to control dimmable power supplies such as Mean Well HLG Series. The resistance can be fixed or variable. If a fixed level of dimming is required, a simple resistor is all that is needed to dim the LEDs to a particular level. If a varying dimmable level is desired, a potentiometer can serve this purpose. By changing the resistance value of the potentiometer, the output current of the power supply changes, and the LED intensity changes. Controlling a single power supply will require a 100K ohm potentiometer for 100% intensity (100K ohm) to approximately 10% intensity (10K ohm) based on where the wiper is positioned. 1-10V Dimming: 1-10V dimming can be used to control dimmable power supplies such as 12V Mean Well HLG-40~240 Series or 24V Mean Well HLG-40~240 Series. This type of dimming control is an older style for compatible dimmable power supplies and is being replaced with 0-10V dimmer control. 1-10V dimming control works by varying the voltage from 1-10 VDC. A 10-volt signal on the dimming wire will allow for maximum current to flow to the LEDs for maximum intensity. A 1-volt signal on the dimming wire allows 10% of the current to flow from the power supply, which generates approximately 10% of the maximum intensity for the LEDs. 0-10V Dimming: 0-10V dimming can be used to control dimmable power supplies such as 12V Mean Well HLG-600 Series or 24V Mean Well HLG-600 Series. This type of dimming control is the most popular and newest style for compatible dimmable power supplies. 0-10V dimming control works by varying the voltage from 0-10 VDC. A 10-volt signal on the dimming wire will allow for maximum current to flow to the LEDs for maximum intensity. A 0.6-volt signal on the dimming wires allows 6% of the current to flow from the power supply dimming the LEDs to approximately 6% of full intensity. 0-10V dimmers can be found here.	0-10V

Standards And Certifications Standards and certifications comprise a vast number of companies and compliances that serve specific purposes—primarily addressing safety, environmental impact and energy efficiency, and sanitation. They are divided into categories for each product type and certification type to allow for very specific qualifications related to each product. When this system is being used as intended, it gives consumers, installers, suppliers, and anyone else that may be involved confidence that the product is safe and will work well in their application. The most common UL and ETL certifications relate to safety and installation, although they do also provide some sanitation-related certifications (using NSF standards). Another common certification body is the DLC, which specializes in certifying the performance of a light—mainly related to environmental impact and electrical efficiency.
