Fluorescent tube lifetimes and
The Osram high output T5 tubes fitted as standard meet color specifications for at least 10 000 hours. Average tube life is 20 000 hours, but note that tube life will vary depending on operating conditions.
Each power off/on cycle reduces tube life by approximately 30 minutes. To optimize tube life when controlling via DMX, do not dim tubes below DMX value 3 (i.e. approximately 1%) when they are not required in the color mix. To optimize tube life in stand-alone mode, program color-changing cycles that run as slowly as possible. For more detailed information on maximizing tube lifetimes, see the Martin website at http://www.martin.com/service.
Achieve optimum tube performance by ‘burning in’ new fluorescent tubes, i.e. running them for 100 hours at full power.
Excess humidity inside the luminaire can be experienced if: • Seals are affected because covers are distorted or not correctly fastened • Cable glands are not correctly assembled and tightened • Cable diameters are not correct for cable glands • Blanking plugs are not correctly fitted and tightened • Cables open into damp or wet locations (e.g. poorly sealed junction boxes), which will encourage moisture to pass along the cable into the luminaire.
The Cyclo IP65 Directional is fitted with a self-purging valve that gradually expels moisture as the luminaire heats up and cools down in normal use. To eliminate condensation rapidly (after installation, for example), run the luminaire at full operating temperature in dry weather conditions for a minute

or two with the front cover removed so that air circulates, then refit the front cover while the luminaire is hot. If you do this: • The exposed internal components present a risk:, so block public access.
• Ensure that no dust or objects enter the luminaire while it is open.
Operation in extreme ambient
Do not operate the Cyclo IP65 Directional if the ambient temperature exceeds 40° C.
Cyclo IP65 Directional luminaires can be operated in ambient temperatures as low as -20° C (-4° F), but a combination of low temperature and low dimming level will give a risk of flickering and cause voltage across tubes to rise. In extreme cases, luminaires will shut down power to tubes to avoid damage to components. If this happens, luminaires must be reset by powering them off and on again before tubes can be restarted.
Flickering can be avoided at ambient temperatures below freezing point if luminaires are operated so that they generate their own heat and maintain tube temperature at or above freezing point. For best low-temperature dimming performance: • As soon as the ambient temperature falls below 0° C (32° F), apply power permanently to luminaires. If light output is not required, reduce output by dimming tubes instead of shutting down power completely.
• If flickering occurs when dimming, increase the minimum dimming level.
• If flickering occurs when dimming luminaires after startup, start luminaires at full power for several minutes.
As a general rule, the higher the light output, the lower the ambient temperature luminaires can tolerate.
