Dimming Megaman led bulbs.

[Mork]

Has anyone out successfully dimmed 56w or more of megaman dimmable bulbs(8x7wcandle bulbs). I would really love to know, because I cant.

 

[Marvo]

Can you give a link to the exact lamps (bulbs) please? What issues are you having when dimming them ie frequent failures, flickering, etc. Also some info on the exact dimmer you're using would be helpful.

 

[Mork]

Bulbs 7w 50m/A 230v , dimmers so far Richmond 500/750 and Hamilton(both recommended by wholesaler), the lights are flickering on any dimming range.

 

[Marvo]

The dimmer is very oversized, this could be the problem. 56watts of load on a 500/750 watt dimmer is insufficient. Try a 100/200 watt dimmer and also refer to the Megaman lamp specifications to find if a leading or trailing edge dimmer is required.

Megaman do not seem to recommend any more than six lamps for their recommended dimmers though they do not list the 7W lamps.

Try a danlers res load on the circuit

Also try taking a lamp out and putting one normal halogen in this will give you a idea if u res load will work.

Your to near the base load of the dimmer I think.

I had 6 7w that wouldn't dim without a resload even after I changed to recommended dimmer (varilight)

In another room had 9 and they dimmed ok.

Swap a lamp out for a halogen and you'll find out

bury the bulbs in the garden. they'll be dim then.

Have you tried speaking to megaman? I have!

I had issues with 6w GU10 dimmable lamps and found that varilight dimmers with a minimum load of 10w do the job without flickering. They are trailing edge

A lot of manufactures and importers are trying to sort this problem, but they are using inductive and resistive dimmers, which wont work. Most are now using Silent inteligent dimmers, main sockest TLC, They are a trailing edge electronic dimmer working with a minimum load of 2.5watts, which is low. The said dimmers are now recomended by Phillips, Masterled, Toshiba.
Certainly worth a try

Megaman have recommended to me, the Varilight JQP401W, which im off to fit this morning.

Ill report back and let you know.

Jason,

I have spoken to Megaman about this and the JQP401W dimmer by varilight comes in various batch numbers. A or B will not work. F or G will. There is a label on the dimmer module. It may work initially then behave eratically. The dimmers can also be reset. I have emails from varilight on this. Ultimately im trying to find a 230v GU10 that works with a 230v dimmer. PM me and ill try and send you some info from megaman and varilight as it sounds like we are in the same boat and may be able to help each other!

 

[Mork]

Thanks for all the above,usually I use aurora bulbs with aurora dimmers and never had any issues, the megaman bulbs were purchased by the customer like a fool I said it wasn't a problem to dim them, the previous dimmers installed were all recommended by megaman, but big thanks to Dave I contacted magaman myself and for the load & bulbs I have they do now recommend the varilight, its already ordered!

 

[Mork]

Big thanks to Jason, sorry almost forgot.

Hi Dave/Mork,

From memory, when the wholesaler got them in, he called me to say they were the incorrect type and he needed to reorder them, which are the ones i fitted today, so i am guessing he initially had the A/B type.

I must admit, when power is first applied, the lamps come on, then go off, and then come on again.

I left them on for a while whilst i was finishing off, and didnt have any issues.

I had 6 lamps on one and 9 on the other.

By the way, these dimmers are rated down to 10W.

So, yes, Varilight JQP401W F/G works fine, and will dim them right down, similar to halogens, although that could be down to the lamp.

I hope thats of some use!
