New technical refinements include protection against both high and low mains voltage and thermal damage. This intelligence protects the electronic control gear from damage if it is operated outside its specifications — such as ambient temperatures below -25°C or lamp cables being too long.
Preheat times for T5 lamps are 0.5 s, and they can be dimmed to 1% of full output. Even 49 W lamps can be operated under the best-possible conditions using ‘smart heating’ to control filament heating, increasing lamp life and reducing the connected load by reducing the heating of filaments.
