Abstract: Brown dwarfs undergo little change in near-infrared luminosity while cooling from L to T spectral types, making the L/T transition (spectral types ≈L9–T6) an ideal region to examine the differences in photometry for binary and single brown dwarfs. We investigated the mean absolute magnitudes for binaries and singles with parallaxes as a function of J–K color in the L/T transition. Overall, binaries are on average 1–2σ brighter than singles of the same color. We discuss the implications for candidate binaries that are apparent spectral blends which span a broad range of luminosities, from the brightest binaries to the faintest singles.
