1. Under any circumstance, the tube with small diameter (tube diameter ≤26mm), that is, T8, T5, etc., should be used instead of T12 tube, which has obvious energy saving and environmental protection effects. 2. In any case, three primary color fluorescent lamps should be used, and halogen powder fluorescent lamps should not be used. The three-primary color tube has the advantages of high light efficiency, good color development and long life. Although the price is expensive (about double the cost), due to its high luminous efficiency, not only the energy saving effect is good, but also the running cost is reduced; and because the number of lamps used is reduced, the cost of the lamps and the ballast is saved, but the lighting system is The total initial construction cost is reduced. 3, the use of high-power lamps: in functional lighting (except for decorative requirements), should choose not less than 4 呎 (approx. 1200mm) long tube, T8 type 36W, T5 type 28W, its light efficiency is higher. 4, the general situation should adopt medium color temperature lamp: the color table of the light source (represented by the relevant color temperature), in addition to the special requirements of architectural color, generally can be determined according to the illumination level: simply speaking, high illumination (>750lx) should use cold color temperature (High color temperature), medium illumination (about 200 ~ 1000lx) with medium color temperature, low illumination (≤ 200lx) with warm color temperature (low color temperature). Because warm color warm light makes people feel comfortable under low illumination, and feels hot under high illumination; cold color warm light feels comfortable under high illumination, and feels dim and cold in low illumination. The illuminance of most places is between 200 and 750lx, and the medium color temperature light source is better; and the fluorescent light effect of medium and low color temperature is higher than that of high color temperature lamp, which is also beneficial to energy saving.
