CL RTM 1 is Carden Lighting's magnetic retrofit kit: LED light bars that attach magnetically inside the fluorescent fixture already in place, plus a driver that powers them. Pull the lamps and ballast, set the bars, wire the driver, the housing, the ceiling and the conduit all stay. Available in 2 ft and 4 ft, with 2, 3 or 4 bars depending on fixture width, field-selectable wattage (36/25/18 W or 60/50/36 W), color temperature selectable among 3000, 4000 and 5000 K, universal 120–277 V and 0-10 V dim-to-off. DLC 5.1 Standard listed, 5-year warranty. Carden manufactures: length, bar count and wattage group are set per project.

Where it's used
Corporate offices with installed fluorescent troffers: the product's natural use. It converts the linear and T-grid troffers already mounted to LED (the tubes and ballast are removed, the bars attach magnetically and the driver is connected) without removing the fixture, touching the ceiling or redoing the conduit. The conversion is done fixture by fixture, at night or in stages, with the floor in operation.Schools and universities: classrooms, labs, libraries and corridors with installed 2 and 4 ft troffers. It allows upgrading building by building with a phased budget and standardizing the color temperature per building, since the CCT is set on site with the selector.Clinics and general hospital areas: exam rooms, corridors, reception, records and administrative areas. Because the housing stays in place, each area takes minutes, with no construction or dust, and service keeps running.Retail, big-box and back rooms: sales floors, store stockrooms, docks and packing areas with existing linear troffers. Selectable wattage lets you raise the light level in display areas and lower it in back rooms with the same kit.Light industrial facilities, workshops and covered parking: runs of linear troffers over shelving aisles, packing lines and workshops. The 4 ft version with 4 bars covers wide troffers that used to hold four tubes.Government and corporate buildings upgrading floor by floor: the same kit fits troffers of different generations in the same building, because it attaches magnetically and does not depend on the original hardware.Completes the retrofit trio in the Carden catalog, which until now offered two of the three options:CL RTB, Retrofit Bulb: replaces the lamp (corn-type LED bulb with E26/E27/E39/E40 base) in an HID fixture.CL RTT, Retrofit Tube: replaces the tube (T8 bi-pin G13 LED tube) in the existing lamp holder.CL RTM, Retrofit Magnetic: replaces the entire internal optical and electrical assembly of the troffer (LED bars + driver) while keeping the housing. It is the way to go when the housing is sound but its internal technology is not.Compared with CL RTT 9 (T8 tube): both upgrade without changing the troffer, but the tube keeps the lamp holders and the original tube layout, while this kit removes the lamp holders and ballast and redesigns the internal distribution with 2, 3 or 4 bars.Compared with the complete linear families (CL LM, CL PL, CL TRF, CL LR): those replace the entire fixture. CL RTM 1 is the alternative when the client wants to keep the troffer and the ceiling.
Featured benefits
  • The troffer stays where it is: no need to take down the fixture, open the ceiling or redo the conduit; the conversion is done from below, troffer by troffer.
  • It attaches magnetically, with no new screws or drilling of the sheet metal, so the same kit fits troffers of different brands and generations in the same building.
  • The wattage is adjusted on site (36/25/18 W or 60/50/36 W): the same kit raises the level on the sales floor and lowers it in the back room.
  • Three color temperatures to choose from (3000, 4000 and 5000 K) to standardize the lighting criteria of the whole building with the same fixture.
  • DLC 5.1 Standard certified: qualifies for incentive programs in the United States and supports efficiency requirements in bids.
  • Installs with the space in operation: each fixture takes minutes and creates no construction or dust, so offices, classrooms and clinics stay in service.
  • 0-10 V dimming with full dim-to-off and universal 120–277 V to integrate with any existing control system.

Photometric specifications

Luminous flux
3,852 lm (2 ft · 36 W) · 3,888 lm (4 ft · 36 W) · 6,480 lm (4 ft · 60 W, 2 and 3 bars) · 6,600 lm (4 ft · 60 W, 4 bars): maximum values per configuration
Efficacy
107–110 lm/W
CCT
3000–5000 K
Distribution
Downward and diffuse, determined by the existing troffer that houses the bars (the kit has no optic of its own)

Physical, materials & mounting

Dimensions
Nominal length of the LED bars: 2 ft (≈610 mm) and 4 ft (≈1,220 mm)
Hardware
Magnetic attachment built into each LED bar is the kit's mounting method; no screws or drilling into the troffer needed
Mounting
Retrofit inside the existing troffer: the fluorescent tubes and ballast are removed, the LED bars attach magnetically to the troffer's inner sheet and connect to the kit's driver. The troffer, ceiling and conduit are kept
Packaging
10 kits per box
