Onyx to be back lit

Any special consideration I should think about. I have done extensive slab work for 10 years, but never managed to do a back lit onyx install. Just looking for anything special I might not have thought of.

Also looking for about 300 sf of white onyx slabs 3cm or 2cm.

Thanks,

Erik

Fort Collins backlit Onyx countertops

How are you going to backlight them? With led ropes or by some other means?

backlit

Yes, but I don't want to see the rope lights like in the pictures above.

Was that 2cm or 3cm material?

I am using white onyx.

thanks

That's 3cm onyx. The problem is you will somehow need to diffuse the light between the led's and the onyx. Not sure how translucent the white onyx is but the honey onyx in those photos you could read a newspaper through.

The other option given for those particular countertops was that the slabs be placed on a 2 cm semi-opaque plexiglass and the nose formed seperately and epoxied to the front so the entire slab above the cabinets would be about 5cm. The semi-opaque plexiglass used to diffuse the led's more so they don't look like what they are - light ropes.

He didn't want that, he wanted what you see there. Not my house, eh?

The problem with trying to diffuse the light enough is the limited space beneath the slab. Dunno if white onyx reduces that problem or not.

The one backlit onyx job we did we had the slab sent to the custom lighting designer and he made a tube light which lit the stone evenly. He took into consideration the varying densities of the stone, its natural light and dark spots. When he delivered it, he had it in a light box the same depth as our wall cavity to prove it worked as well as he said. And it did.

Backlighting Onyx with LED panels

Hi there, I am a designer at GPI International. We actually specialize in exactly what you are talking about... we manufacture natural stone that is cut down to a 2mm-8 mm thickness, then laminated to glass. This allows the stone to pass light, while maintaining a lightweight and easily installable product.

To achieve backlighting, our FLAT-Lite LED panels are pressed to the back of the stone to provide backlighting... the panels are 8 mm thick. We work with you on your specific application to figure out how we can eliminate hot spots, and what spacing is best based on the type of stone, translucency, thickness, etc.

Just thought I'd let you know- we understand that backlighting stone can be quite a hassle. We have been in the natural stone industry for over 14 years, and our expertise in combining stone and lighting is unmatched. Of course, backlighting can be achieved in several different ways- our system is best used in tight spaces where it is difficult to sufficiently diffuse typical light sources.

Good luck with your project, please visit us our website gpidesign.com and give us a call if you have any specific questions!

Welcome, Caitlin.

You weren't able to post your link because of an anti-spam measure we have in place, so I lit it up for you.

Questions about such back-lit stone come up here from time to time and I hope you'll stop by to respond to some of those posts. We do like to keep the discussions here on the public forum, rather than private contact, so more members and lurkers can benefit from the exchange.

Backlit stone with LED LIGHT PANEL

Hi All

I use a Canadian made LED Light panel for this application
google "Nu World LED Light panel" for info.

GPI does great work , but if you are looking to buy the LED panels without the stone you will get the best price from Nu World.

Depending on the type of onyx used we have found that adhering the onyx directly to the LED panel using clear silicone works just great. This works well for backsplashes and coutertops, so obviously if you are looking to light a massive 4x8 slab I would not suggest using just silicone

Cheers

Roy

Here's a light fixture that was on a job a while back. It was so heavy, they had to take shingles off the roof to brace and bolt the brackets. No attic space above it.

ONYX fixture

Davy

Is this a custom fixture?

If not where was it purchased?

Really nice!

Cheers

Roy, I have no idea. Looks like one could be made without a whole lot of problems.

Backlit an onyx bar a few years ago with xenon festoon lighting (24Volt). The LED drivers were very expensive for what we were looking at. Gave a very good finished result (nice even "wash" of light); changing lamps though is a REAL cusser.

Backlit stone with LED LIGHT PANEL

Roy,
This is not directed at any particular manufacturer, but watch out who you buy your LEDs from. Many companies will fail to balance the power distribution and end up over-burning the fixtures. Also make sure that if you purchase an LED panel or similar product, that there is a heat sink to draw the heat away from the LED bulbs. No heat sink, and the life span drops significantly. Many companies fail to tell you this, though.

GPI isn't always the cheapest, but we have developed ways to run several LED panels (up to about 150 square feet) off of one power supply (a unit that we have custom engineered), can dim our panels, and can even integrate into Lutron or similar building control systems.

Is replacement/repair going to be a hassle if the stone and LED panel are bonded together?

Caitlin

Nu World LED Light panel

Hi Caitlin

You are right , LEDs can be fussy> We have had issues in the past with LED Flex strip. The loads were not properly balance and we had some problems.
Now we always balance the loads evenly to ensure max life span. The issue that you raise with the heat sinking of LEDs is a very important one and one that many manufacturers will tell you you dont need. We always mount the flex strip to an aluminum surface.
The LED Light panels are constructed with the heat sinks built in so maybe it is the same technology that you speak of.

Up here in Canada we have to keep all circuits below 5Amps due to the fact that the panels are Class 2 UL fixtures so I wish we were allowed to use one power supply for that many panels, fortunately the designers and electrical engineers that we work with are clued up in this department.

The silicone is just used to hold the panel in place and is not intended to take all the strain of the stone , as a backsplash application the Light panel can rest on the lower cabinets.
For replacement or repair it is usually a bit of a process because the stone will have to be removed any way.
We will usually do a bead of silicone around the edges so it is easy to pry off once the stone is removed.
Also if the rated lifespan is anything to go by we should get 10 years lifespan in a commercial application.

Cheers

R
