Varilight Dimmer max loading

[haptism]

Hi, hope someone can advise. Ive just called Varilight helpline in regards to max loadings on their 300w trailing edge LED single gang dimmer. They tell me that I can have a maximum of x30 10w leds on the dimmer.

Most info out there regarding dimming LED suggests to divide the dimmers wattage by 10 to determine max number of led lamps; I put this to the guy at customer services and he says varilight dimmers are designed differently and can handle the x30 10w lamps. Can anyone confirm or reject this statement.

I never think its a good idea to load dimmers to max like this; the guy at helpline says the inrush of x 30 10w led's wont effect a 300w dimmer, im not so sure.

I think they have given you incorrect information. Your calculation of dividing by 10 is a common method, as you say divide the 300w by 10 to give a maximum led loading of 30w.

That was my thoughts also Westy, just that the guy at technical services seems adamant I could load it with 30 leds. Just wondered if anyone had done this and what the results were. Technology moving so fast now its a pain to keep up

If it's a vPro series, the datasheet for the JQP401W suggests a maximum of 10 LED lamps upto 120w.

I wouldn't worry too much about in-rush current as many of the Varilight dimmers use a soft start when the power is applied.

Yeah wadda they know

When I rang them they said 75% max load on led

Bloody people, I mean its a bit much really giving out info thats wrong, and they make the stuff !

I give up

Why would ANYBODY want to put 30 LED lights on a single dimmer?

That's plain daft IMHO

 

[chris gray]

I had no end of problems on one job where we’d fitted total of 50 10w led split across multiple banks.
The led suppliers then put list of faulty fittings out.
I tried every single dinner mod and spoke with every single manufacturer.
Varilight told me not to put more than 75% led loaf in their mods. Which beggars belief that they sell them under the guise that they’re capable of more than is stated on the packaging.

How many LED's are you planning on adding in total on the circuit?

JCC have advice on the maximum numbers per circuit on their installation instructions

Speak to those expensive chaps at Zano, and install some of their offerings.

Thats 'cos they can't handle the latent warranty issues in a few years months time.

Hahah we tried zano. £50 dimmer and suppose to be the dogs do do. Didn’t work

Yeh the zano Zbar 1000w looks like a good offering
