In Table 6.23, a survey of lamps is given for general lighting in industrial plants. Sodium vapour low pressure lamps (point 5.1 in Table 6.23) are not within the scope of the standards for explosion protected luminaires. Incandescent lamps (1.1 in Table 6.23) and blended lamps (2 in Table 6.23) are unimportant for general lighting applications in industry due to their poor luminous efficiency. Therefore, the following luminaire-lamp combinations are the state of the art  [Pg.456]

The specific luminous flux - luminous flux per price unit - however, does not differ significantly between e-luminaires with tubular fluorescent lamps (13.4 lm) and d-luminaires (9.21m to 25.71m). [Pg.458]

Luminaires for induction lamps play a special part with a specific luminous flux of 5.3 lm only, but they are compensated with a multiple operational lifetime and decreased lamp replacement costs. [Pg.458]

For a lighting system, the total costs per year (including costs for electric energy) can be calculated according to  [Pg.458]
