This is why you don't see a heat sink on small 5mm/8mm LEDs but if you purchase a 120v LED replacement bulb, it has complex heat sinks. So, as a result, the majority of controllers are designed for low current/wattage output where LED's are most efficient. Where you will see high output controllers is in purpose built designs such as stage lighting but these lights tend to be VERY expensive and outside the cost range for most holiday lighting people. <br /><br />There are also disadvantages to large floods - not only are they more expensive, less efficient but you loose control because now you might have two floods to light up your entire house but try sequencing a "wave" or chase over the face of your house - it's nearly impossible with two but if you had 4,6,8+ floods, now you can do some intresting things.<br /><br />There is another problem with large output floods, when used on residential houses - houses are not flat. They have protrusions, angles, porches, etc. So, if you have one large flood, you'll end up with LOTS more shadows and poor coverage. When you have a number of smaller floods, you can angle them to get good coverage over the face of the house.<br /><br />David<br />HolidayCoro.comHolidayCorohttps://www.blogger.com/profile/10883064006561550080noreply@blogger.comtag:blogger.com,1999:blog-3156973944979054356.post-91111087358217283692013-03-12T13:11:56.787-05:002013-03-12T13:11:56.787-05:00I am totally with you… Where is the standardizatio...I am totally with you… Where is the standardization??? <br />Try finding a DMX512 controller to work with 50W or greater RGB LED. The RGB LED’s require 28V-38V for Green and Blue! Yet all the DMX512 controllers are 24V… do you use a Boost or step up transformer etc? How can they sell LED’s requiring one voltage and not match DMX controllers voltage? Then you have the heat issues… many housing manufactures say they can handle the heat… and you find out their version of handling the heat is about the same temperature as your range top! Just because they say it can handle the wattage does not mean the heat. Ratting of the LED at 50W does not mean output of the LED in lumens… it means how much power the LED draws… make sure you read the lumens output! And why doesn’t the LED’s list their thermal requirements or what their thermal output is?<br />Man … This is NUTS! <br />Anonymousnoreply@blogger.com
