Hello everyone
I'm considering buying some Led PAR lights to replace my 1000 watt incandescent PAR. I've been looking at several models, but none (except the VERY expensive ones) gets equal in power to the traditional PAR. Anyone using afordable LED lights with success? Thanks |

Yes and no. They are VERY good for control and getting an almost unlimited range of color out of one light and position but they just don't (at this time) have near the output of a 1k par. Now keep in mind that with a lot of saturated color you're only getting out maybe 5-8% of the output so that evens it out a little bit depending on the color you need. I do use them constantly but usually in banks of 4 to get the punch I need which is expensive but they are great for the control.
I will say with the rate that LED technology appears to be advancing, that within a few years they will be aa LOT brighter and closer to traditional fixtures. There is already a lot of talk on an LED Source Four coming out soon. It's all on the way!

Ultimately you need to get 4 to 8 of them and play with them along side the other lights to see how you like them. as an example, these: http://www.americandj.com/ProductDetails......tSearch= are relatively inexpensive and brighter than the ones I paid more for only a few years ago. With technology advancing so rapidly, there is always some experimentation involved!

These lights are even brighter than the adj lights you might call and ask about them..

The Chauvet SlimPAR 64 Par Light has double the LEDs as the ADJ listed above for only about $30 dollars more. You can fnd them for $129

There are new units coming out daily but you really need to look at the photo metrics to get anything quantifiable. Just like any lamp, It's not necessarily the number of LED's but their brightness. A string of hundreds of Christmas tree lights aren't brighter than a single follow spot.
Chauvet is a well known and economic source. Color Kinetics have very bright fixtures but also cost a lot more. Shop around but always judge based on actual light output, not the number of LED's alone.

You are absolutly correct. I was just trying not to get to technical. The Chauvet SlimPAR 64 Par has a Lux of 3,640 @ 1m. I am not sure what the ADJ profile is but compared to the Chauvet SlimPAR 56, with a similar number of 10mm LEDS runs Lux: 1,290 @ 1m. Another thing to think about is beam and field angle (how much area do you want to cover)
The ADJ has a beam angle ot 30° (Covers more area) versus Chauvet SlimPAR 64 Beam angle of 23°. Of course the more area you cover the lower the lumens. |

It is important to know the brightness, but often manufacturers do not clearly set out the candles or lux for each led fixture.
Just to compare: How many Lux has a "standard" 1000 W incandescent PAR? |

Things are more like they are today than they've ever been before...

I like this article it is much simpler than the ones I would have pointed to. To answer the question above a 1000W Par can will put out between 10,000 to 15,000 LUX (at one meter) depending on the fixture.

Yes, but you also have to factor in that some saturated gel will cut about 95% of the output. If you're looking for white light, traditional PAR's are hard to match for output, but the color work is where LED's shine.

Absolutely! I have not found an affordable LED that can replace traditional PAR lighting for White flood or Spot. The LEDs are great for adding color or to supplement your PARs so you can lower the intensity and therefore reduce the power requirements and heat the PARs generate.

That depends on the suggested use. For coloured scene lighting, especially with colour changes, use LED pars. Look for the latest models, because the luminaires get brighter every year. Moving lights with leds could also be useful.
For lighting yourself NEVER use leds. White led lighting always looks horrible on human skin when compared with tungsten lighting. There are technical reasons for that. Light with a Plancks curve and a warm colour temperature is perfect for enhancing human skin. Leds with warm white colour never look as good. So for front lighting you should always use tungsten or incandescent lamps. But you can improve you lighting. PAR 64 can be replaced by ETC PARs with 575 watt lamps. The lenses are made from polycarbonate and can be changed for different beam angles. The luminaires are nearly as bright as PAR 64 with 1000 watt. But the ETC Pars are much lighter and smaller, the spare lamps are not as big and heavy too. |

Never heard of ETC PARs before. Will investigate it a little bit there. Thank you very much!

They are called source four's. They come in pars, parnels(fresnels) & ellipsoidals. They come in 570 or 750 watts and can easily compete with regular par cans. As abrell mentioned, instead of carrying different bulbs for various beam angles, you simply trade out the lens, which packs flatter and is more resilient than carry different bulbs. Even better, it's the same bulb between all the various fixtures par, parnel, ellipsoidal.

The LED lights must be getting better. I was at a Duke Tumatoe concert over the weekend and 10 LED cans were used to light a trailer stage, at night. Everything on stage was well lit.

LED technology is definitely getting better and is definitely the way the industry is heading. I'd recommend doing your research before making a purchase as not all fixture are built the same. I've worked with some performers who have bought the cheapest fixture they could find and you definitely get what you pay for.
