4. Cov chav kawm yuav tsum siv lub teeb ci uas muaj xim kub ntawm 3300-5500K, thiab xim rendering Performance index ntawm lub teeb ci yuav tsum tsis pub tsawg tshaj 80.
5. Tus nqi sib koom ua ke glare (UGR) ntawm chav kawm yuav tsum tsis txhob siab dua 19.
6. Under the condition of maintaining the average illuminance value of 300lx, the current value of classroom lighting power density should not be greater than 11W/㎡, and the target value should be 9W/㎡.
