Service
Warning! Read “Safety information” on page 4 before attempting to
install, operate or service this product.
With long-life fluorescent tubes and no moving parts, the Rail Light is almost
service-free. However, occasional cleaning is necessary to maintain the
appearance and performance of the product.
The Rail Light’s Osram T5 tubes have an average lifetime of 20 000 hours,
but tube life will vary depending on operating conditions. As an approximate
rule, each power off/on cycle will reduce a tube’s lifetime by 30 minutes.
Fluorescent tube replacement
Warning! Isolate luminaires from power and ensure that power cannot be
reconnected before replacing a tube.
To change a tube:
1. Isolate the installation from power and make sure that power cannot be
connected accidentally.
2. See Figure 12 on page 20. First, press the upper edge of the
polycarbonate front cover (A) in to release it from its retaining channel in
the luminaire profile. This operation can be carried out by hand, but the
special clamping tool supplied with the Rail Light can save time and ease
the operation.
3. Lift the cover down and away from the luminaire.
4. Pressing on the tube with both thumbs, twist it 90° in either direction to
release it from its sockets, and then remove it.
