The Claim
Incandescent lamps exhibit the lowest melanopic illuminance (median 8.2 lx) and melatonin suppression potential (1.5% MSV) among common household lamps due to their minimal short-wavelength spectral output, resulting in the least disruption to circadian rhythm during evening use.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Incandescent light bulbs are the least likely to mess with your sleep at night because they give off less of the blueish light that tricks your brain into staying awake.
See the scientific wording
Incandescent lamps have the lowest melanopic illuminance (median 8.2 lx) and melatonin suppression potential (1.5% MSV) among common household lamps, due to their minimal short-wavelength spectral output, making them the least disruptive to circadian rhythm in the evening.
What the research says
1 studyStudy: Home lighting, blue-light filtering, and their effects on melatonin suppression
The study found that incandescent light bulbs affect nighttime melatonin the least, just like the claim says, because they give off less blue light.
