What is CRI?

What is CRI?
IRC, or color rendering index, is a standard for measuring the quality of light. More precisely, with what precision do the colors appear under a source of artificial light? So what do you need? Here are some tips to help you make the right decision to choose the right IRC for your application.

First of all, rest assured, LED is a high quality light source. Compared to some of the lights we are used to in the past, metal halides, high pressure sodium, low pressure sodium, LEDs, produce high quality light. And we defend the saying: High quality lumens = less lumens. In other words, you need less light when it is more precise.

However, lets talk about numbers. The IRC is a scale between 0 and 100. 100 is daylight, the norm of sunlight. Artificial light always tries to reproduce the quality of the sunlight.

IRC affects how colors are represented in light. More specifically, it really affects the red color. Looking at a bowl of CRI 70 gum balls and the same bowl under CRI 90. For most, it's hard to tell the difference as long as you do not focus on red gums. Under CRI 70, the red is dull and grayer compared to the sharpness of the red under CRI 90.

And typically, the CRI diodes 90 are more expensive than the CRI 70 diodes.

So, what do you really need?

1. Retail sales
If you are a store like GAP or a car dealership, you want a high color rendering index lighting. Bright colors mean that the product leaves the ground. So it makes sense to invest in high quality, high noise lighting. Think 90+ CRI.

2. Factories and warehouses
The bright areas are probably more important than the correct representation of the red color, unless your production area requires quality assurance stations where color control is important. In most cases (99% of the time), you can get by with the 70+ CRI standard. The standard CRI for most of the berries we sell are 70-75.

3. schools
The majority of schools can use the 70 CRI standard. Classrooms, hallways, gyms are all candidates, unless the gym is a video production site. If you have an arts and crafts room, you can also consider a higher CRI value.

Conclusion
For the most part, 70+ IRC is fine. There are exceptions, so if you do not know what you should have for your location, ask us.

Optics for Highbays LED lights

Optics for Highbays LED lights Read it before logging in and buying high floors for your store or plant. Choose the wrong optics and you may end up with a lighting nightmare. So, what is an optics? This is the way you can manipulate the light to distribute it in a different way from the native output. • You may want to reduce the beam due to high ceilings. • You may want a wider distribution because the design of your light is not optimal. • Parts of your installation may require narrower and wider beams. So, what should I choose? It all starts with a lighting design. If you have a scale drawing of your area, you can import it into the  lighting design software which is from many best LED manufacture company providing online. They define the scale, determine the optimal fc measure and they will trying to achieve, and begin the design process. Two things will tell them when they reach the goal. 1. They got the average number of synthetic candles you

Calculation of cost savings for outdoor lighting

Calculation of cost savings for outdoor lighting Have you heard and probably even thought you can save money by choosing LED technology? But how much? This tip will guide you in the calculations What do you currently have for lighting? Understanding what your current lights are is the key? 400W? 1000W? Ballasts? Keep in mind that most HID lights have a ballast, and that a ballast consumes 15% more than the bulb consumes alone. So, if you have 400W HPS lamps, chances are you will consume at least 460 watts per device. What will be your new LED solution? As stated in many previous tips, it's easy to switch to LED technology if you return ghost candles in watts. Determine the appropriate lighting levels, then find the best solution to meet your needs. This is how you get to your new fixture and the watts it consumes. Put all together So, if you go through the first two steps (trick - we can make it easy), how do you calculate your savings? Suppose, for example, that you

Discounts for LED lights

Discounts for LED lights Discounts can reduce the cost of buying if you are in the LED market. Here are 5 tips to remember about LEDs and discounts. 1. Discounts are granted by utility companies Whether you qualify for a discount has everything to do with your utility company - the same company that you buy electricity. They set the rebate programs, the amount of the rebate and the amount they are prepared each year to distribute as a rebate. So it's best to do the research (read Tip 5 to find out how to find it easily) 2. Discounts apply to Design Lights Consortium products Most utilities will only see rebates on qualified products under the DLC program. Look for the DLC symbol on the most of manufacture company website to find out which products have been qualified. DLC products are all guaranteed. 3. DLC has 2 programs: Standard and Premium The Design Lights consortium defines the standard and the lamps are subject to the approval of one of these stand
