Sorry for the long post and apologies if this is a newbie question. I removed the variable resistor and used the v control of the Grafik Eye to control this.
LED drivers not giving out correct voltage. Apr 24, at 5: Thanks Matt, I went for the constant voltage in the end. Standard transformers cannot be used with LED bulbs. You might what to have a look at ‘constant current v constant voltage’.
Correct LED Driver – Constant Current or Voltage
Matt2Apr 25, Now that 12V LED spotlights are becoming more common, a wide selection of dedicated LED enabled transformers are coming onto the market. Share This Page Tweet.
Mar 12, Messages: Apr 26, at 3: Well i was probably no help just thought i would try to clarify things a little and maybe you will be able to figure it out now I have installed a Lutron Grafik Eye Integrale to control and dim LEDs but there was quite a lot of head scratching to be done and a few bulbs were damaged in the process.

Hey I was just looking at the drivers you were looking at,, and i’m not too sure how your lights work or whatever, but i halolihe that the drivers were both non-dimmable Posting a message to the forum will remove the above advertisement. Fortunately voptage dimmable LED drivers are coming onto the market. The power supplies that I used were supplied with a wall mounted variable resistor to control the dimming, this was effectively varying a control voltage and causing the lights to dim.

I’m not sure what kind of lights you have though, if they have a plug, and the plug is transforming halolits voltage to DC instead of AC, maybe voltagge just low voltage fixtures, but i never heard of them transforming to DC.
This driver is fitted with overload protection, short-circuit protection, and surge protection, and comes with a full 3 year guarantee. Be very careful with Lutron and LEDs. Apr 25, at 6: Are the mr16 the lap LAP 12v Led marked “direct replacement” If so I have had trouble with these they work ok on the old transformers perfect.

So suspect they have some sort of regulating circuit built in for the ac from the trannies which uses up some power. Apr 23, at 8: Do you already have an account? If you only have a normal Lutron Grafik eye you must make sure that you turn off soft start fade to on and fade to off or you risk damaging both the Lutron and the transformers. Also there’s often derating figures supplied with them. Do you already have an account?
