Block Blue Light
ULTIMATE XXL review
The largest panel we track. Its measured peak came in at 95 percent of Block Blue Light's own spectrometer figure and 45 percent of their solar-meter headline, which is the whole argument for reading the smaller number.

What we like
- 1200 dual-chip LEDs across 71 by 24 in, genuinely full body without moving the panel
- Publishes both the solar-meter and spectrometer readings with distances attached
- UL IEC60601 certification alongside CE, UKCA and FCC
What to know
- Four and a half thousand dollars before a stand
- The page contradicts itself on the red wavelengths, listing 590, 630 and 650nm in one place and 590, 630 and 660nm in the spec block
- 89 lb and 71 in tall needs dedicated wall or floor space
