I am searching for an Electronic Low Voltage, 3 way Dimmer that will handle 600 watts.

I know about the Lutron Maestro series, but would prefer to avoid the costs associated with these units.

I am in a situation where the sparky on the job mistakingly wired two interior zones of pot lights to one feed. The load is now 525 Watts, significantly over the 300w rating of the Lutron Diva DVELV303P unit I was wanting to use.

Any assistance would be appreciated.

Have a great day.

What brand of interior cans use a elv tranny? Just curious I didn't know any of the big names were using ELV? The masestro's aren't that expensive are they?

I specify and use Contrast Lighting for about 99% of my interior projects. If not Contrast then Eureka Lighting. I only ever use ELV transformers on interior projects. The hum associated with dimming mag. transformers is unacceptable here in the calibre of homes I work in. Remember this is a very quiet, off the beaten path, environment here. In an urban environment there is enough ambient noise making its way through the buildings that you can get away with mag. transformers. Not here, it is dead silent and the last thing I want my clients enduring is the hum associated with mag transformers being dimmed. In some great rooms I have 20 - 30 recessed lights on several zones... imagine the combined hum of those if they were magnetic!

The maestro dimmers are not really that expensive on their own... but becasue the EC managed to wired up two transition zone together, we now have a 5-way switching situtation! To use the Lutron Maestro line we would need one master and 4 slave dimmers... around $600 plus installation.

Quality mags with quality dimmers don't hum, if you hear anything it will be the lamp filament. SemperFI, Qtran and many other quality transformers don't hum. We just did the lighting controls in a Ultra high end theater with double walls, noise abatement membrane, and full acoustical treatments. It had 45 Iris cans without a noise and trust me the engineer checked at every lighting scene level. With that being said everyone has what works for them, but I put ELV transformers in the same file with the PAR lamps. HAHA

Top quality Lightech ELV transformers located in each fixture housing are the way to go around here. Obviously there are products like Iris, Martini, and others available which may not suffer the same Mag transformer hum that others like Halo, Liteolier, etc have but these are a much higher price point then the Contrast units... Not everybody is willing to spend the dough required for Iris.

Contrast has not let me down yet, and the 3000 series trims are some of the nicest and most dynamic on the market.... all at a price that most clients are willing to accept.

I do see your application and the benefits are obvious.
