Red Sea's ReefLED 90 draws up to 90 W. It is shown here as one curve, not split into channels, so it is set with Intensity only. Below is that curve at full intensity.
Peaks near 450 nm.
Royal blue 60%, blue 20%, violet 7%, green 4%, red 4%, UV 3% and yellow 2% of its power.
With JavaScript on, type the light's height above the water and the coral's depth and the page works out a range.
This is an estimate built from a few hobbyists' readings, not a measurement. The range is wide on purpose, because those readings disagree, for some lights by nearly two times, and one owner's corals burned at a step the low end called small. It is for the spot right under the light; anywhere off to the side reads lower. A PAR meter reading beats it every time. PAR here is in µmol per square metre per second, the unit a PAR meter reads.
Spectrum read from Bulk Reef Supply's spectrometer reading of a ReefLED 90 at the 15,000 K preset (Blue and White both 100%), BRStv Investigates. See the graph.
This is the first-generation ReefLED 90 (2019). Red Sea's English pages now lead to the ReefLED G2 series, so its own page for this light survives in Japanese.
Bulk Reef Supply measured three presets. Its 20,000 K plot, White at 50%, shows as much white light as this 15,000 K one, and its 23,000 K plot, White at 10%, about a fifth, so the labels or the White channel's limit are not what the presets say. The white share here is uncertain; the blue carries about nine tenths of the light either way.

Where its PAR range comes from: Red Sea's own figures for one ReefLED 90 mounted 8.5 in (21 cm) above the water: 500 PAR at the surface and 150 at 50 cm deep. Bulk Reef Supply's reading under one at the same height, 15,000 K preset: 235 at 12 in deep, at the centre, which matches the high end.
