Calesco STD Lighting System
Manufactured in the UK, Calesco adds a high brightness 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 ES 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 100 lamps connect to 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. Calesco lamps comprise a robust acrylic globe and a polished brass filament support structure which is highly reflective enhancing the lighting effect.
A unique option of Calesco is a ring of RGB LEDs around the base. These can be used to add a tint of colour to the Filament or to fade from a traditional lamp to something more surreal or even sinister!
Note that LED filaments are fragile, Although the enclosure is robust, filaments can break if subjected to rough handling.
Typical Installation Example
Main Features of the Calesco STD Lighting System
- Light output equivalent to incandescent 40W (Std) 60W (Hi).
- IP66 rating for long term outdoor environmental protection.
- Robust Acrylic globe.
- Strong filament support structure.
- Polarity insensitive – connects to the cable either way around.
- Option for RGB LEDs around the base.
- Linear current control (not PWM) for excellent flicker free colours when viewed with a video camera.
- Each lamp has a unique address which is user programmed using the hand programmer. Address can be reprogrammed thousands of times.
- Internal fuse resistor prevent single Lamp failure compromising the whole system.
- Standard E27 lamp fitting.
- Polarity insensitive for easy wiring.
- Diameter 70mm
- Weight 68g.
- Wide drive voltage range – 72-82V.
- Current 60mA (Std/W+RGB), 85mA (Hi).
- Wattage Std/W+RGB = 5.0W, Hi = 6W
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 100 Calesco 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 the assigned DMX channels. The system realises individual control of up to 100 lamps with just a single two conductor cable.
