Is a Woods lamp effective in daylight?

Woods lamps are most effective in low-light or dark environments where the fluorescence they produce can be clearly observed. While they can technically be used in daylight, their effectiveness is significantly reduced due to interference from ambient light, which can wash out the fluorescence. Therefore, Woods lamps are not particularly effective in daylight conditions. They are best used in dark or low-light settings to maximize their diagnostic and detection capabilities.
