A kit of 2 LedPARs and 2 Jellymoons on a T-bar with the possibility to mix RGB with Cool White to achieve extraordinarily beautiful solid colours. Because of the 4-in-1 technology and very high power of the individual LEDs we can achieve a very high output with a minimum quantity of LEDs. The lenses on the front mix all colours perfectly without creating shades in the output. The Jellymoons create an amazing double light effect. This together makes for a great combination. The T-bar has been carried out in a compact casing that can fit almost anywhere. The system includes a remote control that simplifies operation and eliminates the bother of programming. Or you can choose to control with an external DMX controller via its XLR In/Outs. The rugged housing is specially designed for bars, disco, night clubs etc 2 PAR cans with 3x 3W 4-in-1 LEDs 2 Jellymoon with 4x 3W RGBW LEDs RGBW Colour mixing 8 DMX channels DMX and Stand-alone mode Master/slave synchronization IR remote control DMX in/output via 3-pin XLR Pre programmed shows Sound activated with adjustable sensitivity Auto mode with adjustable speed Control panel with LED display Included light stand with max height of 2m Colours PAR RGBW, Jellymoon RGBW No Of LEDs: PAR 3, Jellymoon 4 DMX Channels: 3, 6 or 15 channels DMX Connection: 3-pin XLR Power Supply: 100~240Vac / 50Hz Consumption: 60W Max Height: 1.7m (stand) Dimensions: 730 x 200 x 200mm Weight: 5.65kg

FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA Description: The dimming circuit can make the voltage at both ends of the bulb change in the range of tens to 200 volts, and the dimming effect is remarkable. In the circuit, R2, R3, R4, RP1, C1 and VT1 constitute a single junction transistor oscillator circuit, which is used to generate trigger pulses.When the capacitor is charged by R4 and RP1, the voltage Ue increases gradually. When the Ue reaches the peak voltage, e B1 turns on and the voltage on the capacitor outputs a pulse voltage to R2 via e-b1. Because the resistance of R4 and RP1 is large, when the voltage on capacitor drops to the trough voltage, the current supplied by R4 and RP1 is less than the trough current, which can not meet the conduction requirements, so the single-junction transistor restores the blocking state. Thereafter, the capacitor recharges and repeats the above process. As a result, a sawtooth wavy voltage is formed on the capacitor and a pulse voltage is formed on R2. During each half cycle of AC voltage, the single-junction transistor will output this pulse to trigger the gate of the thyristor, which will turn on the thyristor and light up the lamp. Change the resistance value of RP1, that is, change the oscillation frequency of sawtooth wave, thus change the size of thyristor conduction angle, and then change the output voltage of controlled rectifier circuit to achieve the purpose of adjusting the brightness of the bulb.
