Philips Lighting 1178SH – Frequently Asked Questions

1) Can the Philips 1178SH opalex diffuser be used in a shower or steam area?
Yes. The 1178SH is built as a wet location downlight trim, so it can go directly over a shower or spa where the fixture sees moisture and spray. That wet location rating is what separates it from a standard damp or dry trim, which should not be installed inside a shower enclosure.
2) What lamp goes in the Philips 1178SH wet location trim?
One 26 watt CFL, triple tube type. It is a single lamp trim, so the housing needs to be a single socket CFL downlight running a triple T lamp at 26W. A twin tube or a quad tube lamp of the same wattage is a different envelope and will not seat the same way in the reflector.
3) Is the Philips 1178SH a complete light fixture or just the trim?
Just the trim. The 1178SH is the dropped opalex diffuser with a flange, the piece that finishes the ceiling opening and covers the lamp. The recessed housing, socket, and ballast are separate and have to already be in the ceiling or be ordered alongside it.
4) Does a dropped opalex diffuser give even light or a hot spot over a shower?
The opalex lens drops below the ceiling plane and diffuses the lamp, so you get a soft glowing surface instead of a visible lamp image. The distribution is direct, meaning the light throws downward into the shower or tub rather than washing the walls. For a locker room or a spa where the ceiling is the only light source, that downward throw is what you want; if the goal is to light vertical surfaces or a mirror, pair it with a separate vanity fixture.
5) What part number do I give my distributor for the Philips spa and shower opalex diffuser?
Order it as Philips 1178SH. That is the manufacturer catalog number and the part number on the trim itself, described as the 6 3/4 inch basic dropped opalex diffuser for wet location.
6) Can I put an LED lamp in the Philips 1178SH instead of the 26W CFL?
The 1178SH is specified for a 26W CFL triple tube lamp, and that is the lamp the trim and its housing are matched to. Swapping lamp technology is a housing and ballast decision, not a trim decision: if the goal is LED, the retrofit happens at the socket and ballast, and the existing wet location housing has to accept it. The diffuser itself does not change what the fixture can drive.
7) How many 1178SH diffusers come in a pack?
One per pack, one pack per outer carton. For a hotel or multi family bathroom retrofit that means ordering unit for unit, one piece per ceiling opening, with no case quantity to work around.
