Twenty-three viewboxes were evaluated in six mammography facilities. Luminance and illuminance measurements were made with a recently calibrated photometer. Color temperatures were measured with a Minolta color meter. The average luminance for the 23 viewboxes was 2920 nit (lumen/Sr/m2), the lowest value was 1610 nit, and the highest value was 3630 nit. The average illuminance was 40 lux (lumen/m2), with 6 lux as the lowest value, and 97 lux as the highest. The average color temperature was 8400 K with the lowest value of 4900 K, and the highest of 10,900 K.
在六个乳腺摄影设备中对23个观片灯进行了评估。使用最近校准的光度计进行亮度和照度测量。用美能达色度计测量色温。23个观片灯的平均亮度为2920尼特（流明/球面度/平方米），最低值为1610尼特，最高值为3630尼特。平均照度为40勒克斯（流明/平方米），最低值为6勒克斯，最高值为97勒克斯。平均色温为8400开尔文，最低值为4900开尔文，最高值为10900开尔文。
