[QUOTE="Rob Timmerman, post: 74895, member: 172"] Re: Does this product exist? Yep. The biggest issue is thermal management, getting the heat away from the LEDs. LEDs get less efficient as they heat up so the better your thermal management is, the more efficient and brighter you can make your fixture. Things like fixture size and the size of the LED optics also come into play but are of lower concern. (if you didn't care about lifetime or cost, you could build a retrofit for 500W or 1K PARs, but it's cot currently practical) The other big issue is one of use. If you are looking for saturated colors, you can equal a 1KW PAR with a ~50W LED fixture (have been able to for some time) , but that's not the case with white light and tints. Those colors require significantly more output, and it's quite wasteful to build a retrofit for white light and then drop a Congo Blue gel in front. And if you want to eliminate your dimmer rack, you need some way of getting reliable data into the fixtures. Most conventional PAR fixtures aren't set up for data input, and the metal can tends to make wireless a less attractive option (the Hue lamps that Bennett linked to use Zigbee, which is reasonably reliable but too slow for the entertainment industry). Caleb - I'd be interested to know who you heard this from (PM me if you'd rather not post publicly). While it may be true in some isolated cases, it's simply not true as a blanket statement. Because in general, a specific power LED will be available for around 5 years (this does vary), manufacturers typically design around the latest and greatest to maximize the time they have between product generations. So a brand new hardware store lamp design is probably using newer LED technology than a 4 year entertainment fixture. Plus, newer LED packages tend to by higher efficiency, higher output, lower cost/lumen, better binning, and can withstand higher operating temperatures. All those parameters are useful when designing products for sale, as a generation newer LED can mean that you have a superior product to your competitor. This is one of the reasons that most of the big LED lighting companies stick with the industry leaders in LEDs instead of using the less expensive products from Korea and China - the cheap LEDs are typically a generation or more behind.
