Block Blue Light PowerPanel MEGA vs Block Blue Light ULTIMATE XXL
The PowerPanel MEGA is the cheaper of the two at $1499.95, so it wins on value if the specs are close enough for your use. The ULTIMATE XXL packs more emitters (1200 against 300), which usually means a shorter session for the same dose.

PowerPanel MEGA
The Generation 5 MEGA measured 91 percent of Block Blue Light's own published average, which is unusually close. The listing has since moved to Generation 6 at the same LED count, wavelengths and rated power, so treat the measurement as applying to the previous revision.
ULTIMATE XXL
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.
