The life expectancy is a guide only and can be influenced by a number of factors - mainly operating voltage.

These bulbs are made to operate in 24.0 volts and not on typical battery voltage (about 25 Volts for a fully charged 24V battery). According to one authoritative source, life expectancy is decreased to 50% by 5% over voltage and by about 75% by 10% over voltage.

On a 'normal' solar system this is usually not too big a problem because with line losses, the operating voltage on load at night will probably be down to around 24.8 volts or less. On the other hand, if you turn on these lights during the day (when the solar panels are charging), or if you have a wind, hydro or generator back up at night, you could be subjecting the bulbs up to say 29 volts!

If you run your halogens off a relatively cheap/old transformer type converter from 240V, you can get over voltage if one bulb burns out or you use less wattage bulbs than specified by the transformer.
Replace any failed bulbs promptly!
