Damp location
LCDL Spectra is the planoⒶRCH PRO+ can-less downlight. The light engine carries its own junction box, so no recessed can is needed; it twists and locks into a round reflector trim held to the ceiling by two spring clips. Engine and trim are separate catalog numbers, ordered as two lines. Three engines cover 10–20 W, 27–40 W and 40–60 W, each with three wattage steps and three color temperatures set by switch before power-on. Trims come in 4, 6 and 8 in; the 60 W engine takes the 6 or 8 in trim.

Spec Footnotes · Lumens and efficacy above are the datasheet's nominal values. Measured photometry on page 4 is integrated from the IES file for the configured trim size and engine step; the files do not record a color temperature (4000K per the quick sheet) and each represents every finish of that trim size.
