PART 4 Ballasts for fluorescent lighting

1.  A ballast for fluorescent lighting must be allocated to a category as described in table 1 in paragraph 3.

2.  In respect of—

(a) the category of ballast shown in column 1 of table 2 in paragraph 4; and

(b) the lamp power shown for that category in column 2 of table 2,

the maximum input value of a ballast lamp circuit shall be the value shown in column 3 of table 2.

3.  Table 1 referred to in paragraph 1—

Table 1

Categories of ballast

Category Description
1 Ballast for linear lamp type
2 Ballast for compact 2 tubes lamp type
3 Ballast for compact 4 tubes flat lamp type
4 Ballast for compact 4 tubes lamp type
5 Ballast for compact 6 tubes lamp type
6 Ballast for compact 2 D lamp type

4.  Table 2 referred to in paragraph 2—

5.  For a ballast for fluorescent lighting designed for a lamp which falls between two values shown in table 2, the maximum input value of a ballast lamp circuit must be calculated by linear interpolation between the two values of maximum power for the two lamps which are closest in table 2 to the lamp in question.

6.  For the purposes of this Part, a manufacturer must establish the electricity consumption for a ballast for fluorescent lighting in accordance with European Standard EN 50294.
