12 / 24 V In-line Dimmer working with batteries, over voltage can occur quite frequently.
As an example – professional video camera batteries which are nominally called 12 V batteries are no longer true 12 V versions but mostly 14.4 V – and when they are freshly charged they provide up to 17 V. The DLDIM-BAT dimmer solves this problem.
The Classic dedolights work with 12 V and /or 24 V special low voltage lamps.
These lamps offer the following advantages:
• extreme high light output for a halogen system with 40 lumen per Watt (standard high voltage halogen lamps only provide approximately 20 lumen per Watt)
• resistant to shock and vibration (which is definitely not a virtue of high voltage halogen lamps)
• drastically lower purchase cost (75 % less)
• longer life expectancy
• BUT: As all halogen lamps which offer very high light output, such lamps are sensitive to over voltage.
