Convert to LEDI’ve got to Mac 500s And I want to convert them to LED has anybody done this if so can you contact me please Michelle

I believe the way that you convert a Mac to LED is:

 

• Put the Mac on eBay
  
• Put the money towards buying an LED fixture
  

 

I'm not aware of any way of converting them.

If I had listened to you, I wouldn't have successfully converted some Miniscans to LED! :D

 

You could in theory convert any discharge fixture to LED just by removing the ballast, ignitor, and lamp, and replacing them with an LED, its driver, and some means of cooling the LED. You don't need to worry about dimming the LED as discharge lamps aren't, in general, dimmed electronically (yes, I know some do, but by no means all of them). They most often use mechanical dimming, which will dim any type of light source.

 

The biggest problem you'll have is how you capture the light from the LED. The Miniscans used condensing optics, so it was fairly easy to repackage the lenses so that they would work with the LEDs. If your Macs have reflectors around the lamp then you will almost certainly have to get rid of them as most high power LEDs won't fit inside them. In that case, you'll either have to make your own condensing optics, or use some off the shelf silicone optics which might not be as efficient as the lenses.

 

I have been looking at fitting some LEDs to wash fixtures, and the LED/reflector/driver setup I've been considering are as follows:

 

CREE CMA2550 LED : https://uk.rs-online.com/web/p/cob-leds/1712932/

Carclo silicone optics : https://uk.rs-online.com/web/p/led-lenses/1805456/

Optics holder : https://uk.rs-online.com/web/p/led-reflectors/1241019/

LED driver (possibly) : https://www.meanwell-web.com/en-gb/ac-dc-single-output-led-driver-mix-mode-cv-cc-with-hlg--100h--36b

 

Hope this helps
