Calesco E14 Lighting System
Manufactured in the UK, Calesco E14 adds a compact filament LED lamp to the Digital Festoon product range. The warm white filaments create an effect similar to traditional incandescent lamps to realise stunning lighting displays with a very simple installation strategy.
Externally Calesco lamps are identical to standard E14 fitting bulbs. Internally they incorporate special microprocessor circuitry to decode Glasson Electronics advanced combined power and data technology and control high intensity filaments. Up to 200 lamps can be connected on a single two conductor cable. Each lamp is independently controllable despite being on the same cable. The system is not polarity sensitive so lamps can connect either way around further simplifying installation.
Calesco LEDs are driven with true linear variable current, not PWM, providing super smooth dimming to make the system ideal for use in studios and situations where cameras are present.
Note that LED filaments are fragile, Although the enclosure is robust, filaments can break if subjected to rough handling.
Typical Installation Example
Calesco E14 Description
Calesco E14 lamps create a lighting effect similar to incandescent and feature an extremely simple installation strategy. The units are based around a 40MM diameter acrylic blow moulded clear globe. As with all the Glasson Electronics products the system has substantial voltage tolerance ensuring there is no loss of intensity with long cable lengths.
Calesco E14 uses a standard E14 (MES) lamp base and will fit with virtually any standard E14 lamp holder. Note that we can supply custom festoon harnesses or wired pelmet holder assemblies if required.The system uses true linear current control (not PWM) to provide flicker free super smooth fading.

Calesco E14 Operation
A system is comprised of a VP or IP series mains driver. The drivers accept universal mains supply and output a DC voltage with the combined power and data signal modulated on the positive supply. As a high voltage is required to drive LED filaments, VP/IP 300-80 and 700-80 drivers output a positive and negative voltage relative to earth to reduce electric shock risk however the output voltage (81VDC) must still be regarded as hazardous and installation should only be undertaken by qualified engineers.
Up to 200 Calesco E14 lamps all wire in parallel from the driver output. The wiring configuration is flexible, lamps can be wired in strings or can be individually wired and connect back to the power unit outputs using terminals or splitters, all that is required is for the lamps to wire in parallel. Prior to fitting into the installation, each Calesco lamp is assigned a number using the hand programmer. The number makes a given lamp unique on the system. Note that multiple lamps can be assigned the same number and will then operate from the same DMX Channels. Once installation is complete with all lamps programmed, each lamp will respond to its assigned DMX channel.
The system realises individual control of up to 200 lamps with just a single two conductor cable.
