Please bear with me on what may seem like dumb questions, I’m a sound guy….
I would like to add some normal incandescant lighting (par56 or some ray lights, small spots, etc) to my small, 8 can, PAR64 LED system. The LEDs are sufficient for wash but the system just needs a little….umph.
Can I combine regular par cans via a DMX dimmer pack? How do I go about that? Do I program that dimmer pack’s channels beyond the LED programming I already have, i.e., my programming ends at DMX channel 128 so the dimmer pack would be set to operate beginning at 129? And, do I set the programming, intensity, etc., the same as I have for the LED pars? Will the lighting operated by the dimmer pack (par 56, ray lights, etc) come up where desired the same as the LED pars? Will all 4 channels od the dimmer pack come up in every programmed scene?
Thanks.

Hi,

I’m looking for advice regarding LED UV lights. I supply UV active backdrops to raves and want to invest in some lighting. I have a couple of traditional 400W UV cannons which take bulbs. I’m thinking in investing in some LEDJ stagewash 18 or LEDJ stagewash 36 units. I’ve got over 20 backdrops, the biggest in size being 15m x 1.6m, but approx 150 m sq in total. Any advice? Or better units than the LEDJs to consider?

Many thanks,

Murray

I take photos / videos of bands at smaller venues around Nottingham, the move to LED lighting has given me a few problems. The ‘purity’ of the colours ( narrow wavelength ) gives big white balance problems. If only the Red of Red, Blue, Green LED is used it drives Digital cameras mad. Digital cameras only seem to see about 4 shades of red and you can not produce any sort of decent colour image from these type of setup ( this is why you see so many black and white live music images, its the only way to get a presentable image). The same applies to using only Blue or Green LED light, only its not as bad.

Do you know if a partial defuser is available of LED lights, it would help mix the light and spread the light in smaller venues ( in smaller venues the cool running LED lights are being installed only 1 metre away from the musicians heads).

I have also noticed an issue with video, a lot of LED lights have a 50 hertz flash. The eye does not see it, but the video camera does, this results in phasing of lighting on the resulting video or even problems focusing as the focusing system starts hunting under LED lighting. This is only a problem with LED’s as they appear to switch on and off a 50 hertz, old fashioned Tungsten / halogen bulbs never had this problem as they took to long to cool down and stop radiating light.

Do you have any tips on how to reduce these issues, I would pass on the advice to lighting engineers at Venues. But part of the problem is these guys are being seduced by the vivid lighting LED’s give.

thanks in advance

Steve

Hi Rob,
mate i will be constructing some tall boy dry bars for a hotel renovation and just wondering what would be the best RGB LED fittings with the most muliple colour change options to use to fully illuminate the inside stems of the bars as i will be rebating the name of the hotel through the craftwood stems for the light to shine through – Dry bar stems will be 1100mm high x 400 x 400 square. I will be facing the cutout outs with clear arylic and obviously the RGB for colour changes – Thanks mate

as long as the the power supply is a constant voltage power supply..the lamp needs 12 v to operate.,, If you want to dim you will need a PWM type dimmer.. If you want to dim and also use dmx to control it, you will also need a dmx encoder, unless the dimmer has an encoder circuit.. Try http://www.liteputer.com.tw/ also http://www.youtube.com/watch?v=YmPziPfaByw and you may want to build your own,, goodluck

Hey I’d like a second opinion, can you use LED MR16 lights in normal low voltage transformer ?

I would of thought it would reduce the life of the lamp

Hi Rob-
My query is…..I’m buying a lighting rig for my son’s band and price wise have came across 2 different types of lighting for more or less the same price…the first one is 2 sets of 4 LEDS (4 each side)and the second is 2 sets of 2(2 each side) BULB type of lamps(with changeable gels) in cans with the option of adding another 2 sets.
In your opinion am I best to go with the LEDS or the more traditional changeable Bulb/gel types
Thanks
Derek

You need to compare the lumen output of the led pars to compare brightness. I may be able to provide this data on the qtx light products I sell.

Hi,
I am in a 6 piece band and we are looking for stage lights. I’m on the LED Par Can vibe, but how on earth do you tell how bright each light is going to be? I always thought it was measured in Watts….but none of the descriptions seem to include the watts!! Im confused!! Sorry if its a dumb question!!

Thanks in advance for your anticipated help!!

Best,
Sue

Hey,

I’ve just been asked to design a light plot for a black and white set. What is the best way to provide lighting but keep the black and white feel?
