Payman LED has an exciting new LED technology for those needing a quality lighting product.
Payman Pahlavan: Hello, my name is Payman Pahlavan. I’m the founder of Payman LED, and I’m the senior engineer for Payman LED. My whole background is lighting design. That’s how I started, doing lighting design for hotels, restaurants, high-end custom homes. And in the last three or four years, there’s been an energy-saving product going on in the whole country and state to state. And there’s a limitation that cities have on our lighting designers to create per square foot wattage allot per type of business. If it’s a restaurant, they allow you certain wattage. If it’s a hotel they allow you certain wattage. If it’s a residence, depending where it is, the wattage is limited.
For example, one of my latest designs I’ve done was a kitchen in Alexander Valley, California, and we could not spec incandescent lamps in the kitchen because it’s highly used area. So we were forced, either LED or compact fluorescent. So because of that, lighting designers like me, were forced to go to fluorescent or compact fluorescent or LED. The problem with most new technologies to replace incandescent lamps are the energy saving that you get does not come with all the lighting characteristics of conventional incandescent lamps. Most people don’t realize that when you go buy compact fluorescent or LED, there are two types of them. There are warm white and cool white. Cool white is your sunlight, sixty-five hundred Kelvin. Warm white is what most people assume is your incandescent lamp, yellow, gold in color. It is very hard to create that in compact fluorescent and LED to have the same color characteristic of incandescent.
If you go to a store and you look at a lamp and it’s a conventional lamp, and let’s say here, we pull out an incandescent lamp which is this. That’s you incandescent lamp. You’re average lamp, A-19 lamp product. This one is an LED. What we try to do is create a light bulb that looks, when inside the light housing, the same as your conventional lamp. The same height, the same shape so it will fit inside the housing identical. So where we start from here. The problem is when you get a lamp like this, generic lamp, most LED products looks industrial finish to it. This would be an industrial look of LED that doesn’t look like any conventional lamp or it has multiple heads on it like this, multiple LED shape. So it doesn’t look like a conventional lamp. So when you put it, the housing doesn’t match the light housing. So it doesn’t create the same characteristic cosmetically if you replace the lamp.
So our goal was creating the lamp first that industrial design was similar to conventional light bulb. So we made different shapes of it. We made a candelabra. We make A-19 product. Then we make power lamps that has the same look as conventional power lamp. The conventional power lamp will look on a PAR-30 something like this. So it has the same industrial design. Once it’s in the light housing, all you would see is the front. So the look of it will be identical.
The problem was creating the color correction. Most people look at the lamp, and when you look at the lamp with the naked eye, you’re looking at the color of the lamp that produces. That color is not the same as the color that gets reflected off of products, whether it’s food, whether it’s a countertop, whether it’s a fixture or a number of things, like a tablecloth, a red tablecloth. The red tablecloth has a different color rendering whether under a three thousand Kelvin light versus under a twenty-eight Kelvin light. So we’re going to show a lamp here, conventional lamp, that as you dim the light in an incandescent lamp, the color at one hundred percent brightness is at twenty-seven hundred Kelvin on incandescent lamp.
So I turn this thing at full bright. It has a very warm color rendering to it. As I dim this light, the color actually changes. It gets warmer. It gets more orange, more red. LED lights and fluorescent light cannot produce that. As you dim a fluorescent or LED, the color stays constant. So if I go ahead and do the same thing from an incandescent lamp to a LED light bulb, let’s try a conventional lamp light this. This is an LED twenty-seven hundred Kelvin lamp. So at first glance, it has the same warm color. While as we dim it, the color doesn’t get warmer. It stays constant. This is a problem when you do restaurants, hotels, and residences because the color rendering does not change.
So the solution is to create a technology that as they dim the light in LED, you get the color constant. The constant on that color, the technology called active color management or ACM, that’s what we created. So we’re mixing the red chip with the white chip, color corrected, and as we dim it, the add quite a different power to them. A simple technology version of it is this demonstration here. You have two different chips that’s already in the direct lighting. You have the white chip versus the red chip. At one hundred percent brightness, the white chip would have more power applied to it. Red power to the red chip. As we go to twenty-five percent and reduce the white chip while we increase the brightness on the red chip to create the same level of color rendering you get from a conventional incandescent light bulb.
That was one of it. So when you guys look at the lamp that you’re going to create and why, don’t look at the light itself. Get the lamp with your hands around it like I’m doing here and compare to it your average lamp and see if your color rendering’s the same. Ninety-eight percent to of the product on the market cannot do this. And the other two-percent is very limited in a high-end DMX stage lighting that can create that. There has not been a product created for consumer market as a replacement product that can create this until now. That was our whole work is being.
The reason I started manufacturing of this product, it wasn’t by choice because I actually went to a different manufacturer and asked for such a technology. And they said it was too difficult or it’s not possible and so on. So for the last two years, we invested a lot of time and a lot of engineering to create our active color management technology. To create a lamp that somebody can pick it up, screw it into a light socket, whether it’s a table lamp, and create a super warm color rendering with active color which is this. Give you the nice warm, as you dim it the color rendering actually gets warm.
Let’s talk about the core of the product. Most LED product on the market uses a common chip whether they’re one watt, two watt, three watt. And they’re using single chip technology like adding multiple chip to get more light output. So you go to a store, and you might find a product like this that has three chips inside of it like this. And you see a bigger version has five or eight or nine to get more light out of it. The problem with products like this is when you point it at the product you want to display, you get a multiple ring effect because you have multiple light sources coming together. And the color rendering, you cannot correct for it because the chips themselves comes directly from the manufacturer, and you cannot put another layer of color correction on it.
The technology we’re using by different manufacturers, one is Sharp which is a single-chip technology. You see a bunch of small chips retain that technology. So to get multiple power out would return more chip on within the single chip. So this is a seven watt and four watt chip. There’s a price difference between them. A four-watt chip is about, market price, twenty dollars, and a seven-watt chip about thirty-dollars. It’s the same chip. So why doesn’t Sharp have a separate model? The only thing they do is they do not, on the circuit board, the circuit board behind it, they do not turn the extra chips on, even though you’re buying the seven-watt chip. So the manufacturing cost is the same, but what ends to the manufacturer like us when we buy it is what’s connected in the back or not.
So the chip starts from a single five thousand Kelvin in temperature, and these color codings that you see are our color correction technology that we added to get a five thousand Kelvin temperature down to twenty-seven hundred Kelvin. Then take it one-step farther and actually color correct it. This way you skin tone doesn’t look green or yellow. Actually, it has a natural feel to it to create a high CRI. So if I point it here and look at my skin tone, that’s the normal chip at five thousand Kelvin. When we flip the switch to our color correction, not only have we warmed up the chip, but we color corrected it for the skin to look like a conventional incandescent lamp.
Alright, so we talked about color correction and active color management. So once we created all this technology, we had to dim it, figure out the circuit board. And once we have all that, we apply it different product types. For example, a standard MR-16 versus a LED. This is a LED MR-16. This is a standard MR-16. So we have the same color correction and mobility of this lamp inside this, using the single chip technology. Most of the MR-16 we see on the market has three of four chips inside of them which is conventionally like this. So same technology. The concept is use the single-chip technology, use a color correction on the single-chip and put dimmable circuitry on it and make sure everything has a high CRI. When you look at a lamp product outside the LED box, look at the CRI rating. CRI is the true measurement on how a real product on a high CRI light product would reflect the same color characteristic back. So the higher the number, the better. Anything above ninety, you are in good shape. You have a very good product at CRI.
The other thing we have is a modular system for commercial lamps, seven-inch cans, most commonly used cans are Juno, Elco, Halo, make seven-inch recess housing. And you want to take the whole module out, the reflector and the lamp, and you put this whole module in. And you screw it in and it replace your light. This uses our active color management technology so it gives you that color dimming control. The advantage of doing something like this you get a lot more light output.
Alright, let’s talk about the wattage savings and power savings. A couple of things happens with that. A standard lamp like this, 75-watt A-19 lamp, most commonly used lamp on the market. Our lamp, 7-watt, this light is actually brighter than a 75-watt A-19 lamp. This is closer to a 90-watt, same housing, same shape, fully dimmable, full color rendering characteristics. So you can figure this out. You have a hundred lamp in a hotel, in a restaurant, and you’re replace the 75 to a 7-watt. Great savings. The other thing it helps you is these lamps don’t create heat. Ninety percent of the energy towards this lamp and toward heat production. Ninety-five percent of the energy went to this lamp went to light production. Big difference.
The customers that want our product, so much for LED, all LED products are going to save you energy. It depends if you want to dim, if you don’t care how it looks, or if you don’t care about the color rendering of it. Our products are for the discriminating clients. People like high-end restaurants, high-end homes, boutiques, food markets, like displaying groceries, to make sure that all of the products they’re selling has the true color representation as the products you see in the sunlight or in a incandescent lamp. So to sell the product or to create the atmosphere, those are the clients that we’re going after. Some of the clients that we have are Ritz-Carlton, Four Season Resort Hotels. Restaurants like Gloria’s Restaurants using our products to create the same color invitation that you get from an incandescent lamp to a LED and get all the benefits of LED, all the long lifespan. If you go to replace a lamp on a conventional light bulb is about fifteen hundred hours. You think about you have a project that has a thousand lamps in a hotel. Just the labor to go change the lamp pays for all the LED bulbs. The reason most people like that has not touched LED is because they have not found a product that gives them all of the benefits of LED while at the same time give all of the benefits of an incandescent light bulb. And that’s what we created. The best of both worlds, the future of light.
