LED par cans fans too noisy!

Recommended Posts

Recently we installed a new lighting setup of:

 

- 4 x Visage LED Multipar Zoom 24 x 8w 4 in 1 RGBW

- 6 x Visage LED Multipar 18 x 10W RGBAW

 

Once all the lights were switched on, noticed that the fan noise was very loud as soon as I started to use the Ambers and the Whites.

Unfortunately these have to be changed as its too noticeable for classical music and presentations, would be fine for a night club or rock concert.

 

Can anyone recommend a good alternative with a silent fan noise? or a way to reduce the fan noise?

 

Thanks,

 

Jason

Jason - usually the best option for 'silent' LED PAR cans is to get the "IP Rated" ones (IE designed for outdoor use).

 

SInce they are in sealed enclosures, they tend not to have fans at all and instead use heat sinks.

 

I'm not sure how the above questions about bar locations and air con help. Clearly changing the air con or building new lighting bars is going to be a lot less cost efficient than 10 new LED PARs.

Bar locations are relevant because if the cans sit a metre from the audience then no matter what, fans are bad. If they are a few metres away then quieter fans might be an option.

 

As far as aircon, it's more around the overall noise floor of the building to know what one can get away with in terms of fans.

 

Anyway, I wasn't asking you, I was asking the OP ;)

 

BTW, the idea of IP rated LED because they are fan-less isn't something I'd considered before. But it makes a lot of sense!

To be honest, there are enough good fan-less LED options out there that considering lower-noise fans would just add complication to the matter!

I would recommend (as I seem to keep doing) the Chauvet Colorado pars, they do an IP version and a non-IP version but both are fan-less. They also have very good non-steppy dimming. At the moment I think they are the best fixtures in their price bracket.

Thank you for all the advice.

 

I think the IP fixtures would be the best option in terms of noise.

 

The lighting bars are between 3 - 7 meters from the tiered seating.

Hold on there a mo...

 

Having an IP rated fixture MAY be more expensive than a non-IP rated one that dos the same job, still doesn't have a fan, but isn't up-engineered to keep out the damp stuff.

 

As has been said already, look at the Chauvet Colorado Tri units. I have 14 in our rig at present and yes, they're very good value and have a choice of nice dimmer curves, one of which emulates a tungsten fade-out. Shop around and see what discounts you can get on multiple buys, but the Chauvet gear is VERY good for the price bracket.

I have some Visage LED MultiPAR RGBAW which I purchased late 2012. They do seem very loud when you have a quite auditorium but that soon gets lot with the Audience noise. I only use them on stage for Theatrical stuff but they do venture FOH for music & dance. I did talk to Batmink about changing the fans, but that has warranty issues. I'm now buying the Chauvet units but its difficult developing decent amber which is why I went for the Visage units originally.

simple circuit to install in led parcan to control fan speed

 

We all can agree that a fan in an led parcan does not need to run full speed all the time.

 

 

In most Theatre applications you might only have 1 colour on at any one time with plenty of cues where the leds might not be on at all so time for the unit to cool.

 

we have developed a fairly simple circuit which can be installed inside an led parcan within 10mins.

 

the circuit will:

 

0% of led on = fan at 0 speed

40% of leds on = fan at 40 %

100% of led on = fan at 80 -100% dependent on ambient temp

 

The fan slowly increases and decreases in speed with changes in temperature.

 

Pm if you would like free info on how to build this circuit and info on components required.

The LEDJ 9P10 are very nice, only 9x 10w over the 10x 10w in the Visage but fanless and are a good fixture which I have had the chance to use in anger.

I don't know of a quiet version of the Zoom pars that I've used in anger so I won't recommend any.

On the back of smalljoshua's recommendation some time ago we have a few of these and they are remarkably good at the price. In fact, I've just ordered a few more from CPC.
