Halo RL4LS9FSD2W1EWH – Frequently Asked Questions

1) Will the Halo RL4 retrofit downlight fit an existing 4 inch recessed can?
Yes. The RL4 is a 4 inch LED retrofit module that mounts recessed into an existing housing, so it drops into standard 4 inch cans rather than requiring a new fixture. If your cans are 6 inch, the 4 inch module is the wrong size for the opening and you want the 6 inch version of the family instead.
2) What does Dim to Warm actually do on the Halo RL4, and do I need a special dimmer?
Dim to Warm lets you use your dimmer to warm the color temperature from 3000K down to 1800K as you dim, so the light gets amber like an incandescent instead of staying one flat color. It works off your dimmer, no separate color control head or app. That 1800K bottom end is candle-warm, which is why this gets specified in restaurants, hotel lobbies and residential living spaces rather than a warehouse.
3) Can the Halo RL4 retrofit downlight be used in a covered exterior soffit or a bathroom?
The RL4 is rated for indoor and outdoor installation locations, so covered soffits, porch ceilings and damp interior spaces like bathrooms are within its listed use. The existing housing has to be suitable for that location too, since a retrofit module does not change the rating of the can it goes into.
4) Is the Halo RL4 downlight ARRA compliant for a federally funded project?
No. The RL4 is not ARRA compliant. If your project has a Buy American or ARRA sourcing requirement written into the spec, this module does not satisfy it and you need to source a compliant downlight instead.
5) Do I need to replace the whole recessed housing to install the Halo RL4, or does it go in the can I have?
It goes in the can you have. The RL4 is a retrofit module, not a complete housing, so the existing 4 inch recessed can stays in the ceiling and the LED unit mounts into it. That is the practical difference from a new-construction or remodel housing kit: no ceiling cutting, no rough-in, and the job stays a fixture swap rather than a demolition item.
6) How much light does the Halo RL4 4 inch retrofit put out, and what wattage is it pulling?
900 lumens at 11W. For a property manager or MRO buyer swapping out old 4 inch incandescent or halogen cans, that is a large drop in connected load per fixture across a floor while keeping usable output for kitchens, corridors and office areas. The 4 inch module is offered in 600 and 900 lumen configurations, so 900 is the higher of the two.
7) How many Halo RL4 downlights can I put on one 15 amp circuit?
Each RL4 draws 95mA, so the current per fixture is well under a tenth of an amp. That is the number to run your circuit math from when you are laying out a large recessed job, and it is the reason a retrofit like this usually lets you add fixtures to an existing branch circuit that was already loaded with incandescent cans. Size the circuit to your local code and the rest of the connected load on it.
8) Is the Halo RL4 a warm light or a cool white light?
Two things are going on. The module's light temperature is listed at 5000K, a cool daylight white, and separately the Dim to Warm feature lets your dimmer take the color down to 3000K and further to 1800K. So it is not a fixed warm downlight, it is a unit whose color shifts as you dim it.
9) What part number do I order for the 4 inch Halo RL4 with Dim to Warm in white?
The 4 inch unit is Halo MPN RL4LS9FSD2W1EWH. That is the single 4 inch configuration of this Dim to Warm retrofit, so there is no finish or lumen suffix to pick on the order form beyond confirming you want 4 inch and not the 6 inch member of the family.
