The multi-voltage lamps and LDC dimmer converters are designed to operate on a wide range of input voltage, in heavy-duty applications. Each consists of a surface-mounting base with a gooseneck lamp permanently attached. The bases have dimmers on the upper surface; goosenecks are offered in a selection of lengths and with a choice of light sources. they are suited to automotive, industrial machinery and other higher voltage applications. The PWM dimmer-converters are also available separately.
The surface-mounting base is a rectangular metal enclosure with a footprint of approximately 75mm x 25mm. Height is approximately 18mm, or 50mm to the top of the dimmer knob, where fitted to the upper surface. By removing two screws from the upper surface, a 'chassis plate' is revealed, which may be fastened to a flat surface by means of fasteners fitted through two screw holes, after which the upper part of the base may be replaced to cover the plate and fasteners. Alternatively the chassis plate may be fixed by to a surface by two machine screws, fitted from the other side of the mounting surface. In some applications, hook and loop style fasteners may prove sufficient. See Littlite Gooseneck Lamps - Mounting hardware for a variety of alternatives, including a magnetic base, clips, clamps and rack adapter.
The gooseneck may be fitted on the 'upper' surface of the base (the surface parallel to the mounting surface), together with dimmer, or on the 'end' of the base (the shortest surface adjacent to the mounting surface).
The CC range of lamp sets use constant-current circuity, enabling the use of a wider range of input voltages (8 - 28V DC) as well as smoother LED dimming. Available in three gooseneck lengths of 153, 305 and 457mm (6, 12 and 18 inches) with a LED light source.
Notes: (1) With 305mm captive lead exiting one 'end' of the base, fitted with a 2.1mm coaxial inlet socket. (2) With 305mm captive lead exiting the surface of the base in contact with the mounting surface, fitted with a 2.1mm coaxial inlet socket.
(3) With hard-wire cord set exiting the surface of the base in contact with the mounting surface.
The MV range of lamp sets have dimmers using PWM (pulse width modulation) to achieve both voltage regulation and lamp dimming, allowing 12V lamps to operate on a range of input voltages (12 - 28V DC). The MV range was specifically designed to regulate and dim lamps such as the Littlite HI and LED series in any combination up to a total of a 1A draw. Available in two gooseneck lengths of 305 and 457mm (12 and 18 inches) with a high-intensity halogen bulb light source.
Notes: (1) With 305mm captive lead exiting one 'end' of the base, fitted with a 2.1mm coaxial inlet socket. (2) With hard-wire cord set exiting the surface of the base in contact with the mounting surface.
LDC Dimmer Converters
These use the MV dimmer to provide dimming control and voltage conversion for all Littlite products. Suitable for automotive applications, specialty vehicles, industrial machinery and other higher voltage applications and operating on an input voltage of 12-28V DC they provide dimming-control for single or multiple LED and incandescent lamps in any combination up to a current draw of 1A.

All lamp sets are available with either a euro-style, level V compliant, 12V power supply with Shuko connector (denoted with an E in the model number) or without power supply (denoted with an A in the model number). For UK operation a Littlite LPS2-4-UK power supply, 51-838, is required. See Littlite Gooseneck Lamps - Power supplies, adapter leads for spare power supplies and power adapter leads. All power supplies are terminated via a 1.8m (6 foot) lead with 2.1mm DC coaxial plug.
Lamp sets with an Energy Star qualified switch-mode 12V power supply with US connector are also available to special order. Please contact UK sales on 0191 418 1122.
