Dinushan Paranavithana Posted January 13, 2020 Share Posted January 13, 2020 What are some good companies which can offer high quality LED recessed ceiling lights with dimmable drivers? Quote Link to comment Share on other sites More sharing options...

zaphod Posted January 13, 2020 Share Posted January 13, 2020 Do any LEDs dim as well as incandesant or halogen? I haven't tried the most expensive LED bulbs but it seems to me that while traditional bulbs will go from 0%-100% maximum brightness, LEDs will go from, at best, 50% to 100% maximum brightness.

Yes they do. I have tried some expensive ones. Using Colorbeam drivers, you can go upto 1% dimming and even 0.5%. Quote Link to comment Share on other sites More sharing options...

Lots of good quality dimmable LEDs bulbs out there. The Megaman range I've used offer useable dimming right down about 4-5% and then max out at about 70% on the uncalibrated 0-100 dimming scale of the C4 dimmers. Once the max and min levels have been set correctly on the dimmer channel's properties to much these lower and upper limits the C4 dimmers offer smooth and usable dimming throughout the 0-100 slider range. So, either you are not buying good enough LEDs or your dimmers are not calibrated correct to match their input level/brighness ratios. tdougray 1 Quote Link to comment Share on other sites More sharing options...
Crustyloafer Posted January 13, 2020 Share Posted January 13, 2020 As Dinushan has also suggested, if you go for more sophisticated control methods such as DMX you can get full control in 0.5% increments across the entire 0-100 range.

Do you need special dimmers? I am using whatever the basic C4 dimmer was about 13 years ago when my home renovations were done. Quote Link to comment Share on other sites More sharing options...

Led prefer that. Not all LEDs prefer that. I would check specs. If the LED spec sheet gives you an option, then you are good to go either way. But running a reverse phase dimmer on a forward phase driver is inviting failure. Someone from C4 would have to chime in, but I believe most ELV/reverse phase/trailing edge dimmers are actually MOSFET and not Triac based. A lot of drivers dislike this type. Still a wave chopping form, just a different method. (I am using my experience with Lutron RA2 here). Quote Link to comment Share on other sites More sharing options...

I'm assuming they are all forward phase dimmers, which whilst they work fine with some LED loads, however I have found most LED loads tend to prefer reverse phase dimming controls. I'm not sure what min and max level adjustments there are on those older dimmers, someone else with more experience of them may be able to contribute and confirm.

Did you use RS232 DMX Engine by Engineering Solutions? In addition to RS232 DMX Engine, did you use any other controller? Quote Link to comment Share on other sites More sharing options...
SMHarman Posted January 14, 2020 Share Posted January 14, 2020 Hi [mention=134442]SMHarman[/mention], What's the controller you used? Did you use RS232 DMX Engine by Engineering Solutions? In addition to RS232 DMX Engine, did you use any other controller? My setup is 5 years old and precedes the ES solution. That ES solution is the option I'd use today and I've considered swapping out for it, but mostly time and some money have that as a lower priority. Mine works and with lighting and family if it works don't break it. Mine is the ENTECH solution that C4 / Extra Vegetables built. Quote Link to comment Share on other sites More sharing options...

Thought I'd buy a couple of these to try out and have to say really impressed with the range of dimming. Opted for the Daylights and the colour is epic also, Great recommendation Crustyloafer 1 Quote Link to comment Share on other sites More sharing options...
