Before you Buy: Create a Light Plan
So, how do you know what the end result will be and not risk making a big mistake?
Create a photometric analysis of your area so you can see the light levels simulated with the new lights. If you have a light meter, take a reading of your current light levels. Too much? Too little? You decide.
We create a lighting simulation of your area. You can compare your current light levels to your future light levels. That way, you will know what to expect after you install your new LED NSF certified fixtures.
NSF Certified Food Processing LED Lighting
Food Processing NSF LED Indoor Light Fixtures are for food processing and food safe environments. They ensure the food remains safe and contamination free. These lights are able to withstand high pressure hot water and the rigors of wash-downs.
Our LED Food Processing Lighting meet all the stringent food grade guidelines. Designed to replace 250W to 750W HID and Metal Halide. These stylish food processing high bays provide bright light for a safe work place.
LED Food and Beverage Processing Lighting
The three most important concerns when it comes to food processing are to prevent:
- bacterial growth
- food spoilage
The lights used for food processing facilities must have a high level of protection. These include airborne dust, effluents, steam, mist, water, oils, grime and cleaning solvents.
The compliance standards may differ for different food and beverage facilities. Food production involves many processes. Processed, stored and preparation may occur in different locations. Each has its own set of requirements. Food and beverage plants are industrial spaces. The light fixtures are different than standard warehouses lights.
Why choose LED Lighting Supply LED Food Safe Lights?
1. NSF Certified Food Safe Lights
NSF = National Sanitation Foundation International. NSF is the certification and regulatory body for food safety in the USA. NSF certification is what commercial food service buyers and health departments look for. LED lights get certified under this program.
Our NSF Certified lights have been installed in both food safe and beverage operations. We can replace 250W to 750W HID lights with our NSF Safe LED Fixtures.
2. Wet Location Fixtures
IP rating designates a fixtures ability to keep out both dust and water. The first digit of the IP score designates dust protection, the second designates water protection. A water protection score of 5 or above helps protect your fixtures from water intrusion.
LED Lighting Supply offers IP66 rated NSF Safe LED Food Fixtures. This ensures your fixtures are water safe for years of trouble free operation. We also offer IP69K linear NSF fixtures for extreme hot water and high pressure spray downs.
IP66 rated lighting fixtures can withstand general jet spray. If they get dirty you can rinse them with water.
3. Efficacy (Lumens Per Watt)
140 lumens / watt
Luminous efficacy is the true measure of a bulb’s efficiency and light output. It indicates the lumens produced for every watt of electricity consumed. LEDs are more efficient than traditional bulbs with a higher luminous efficacy. High quality LEDs have awesome efficacy ratings.
Our food safe fixtures are rated at 130 - 140 lumens/watt.
Trade off between initial cost and long term savings?
A higher efficiency LED product costs more than lower efficiency units. The savings over the life of the product is more than the initial investment needed to upgrade. So if you're looking to maximize savings when converting to LED, choose the higher efficiency product.
4. Color Temperature Options
Color temperature or correlated color temperature, measures the temperature of a light source. The Kelvin scale measures a bulb's color temperature. Bulbs with a low color temperature produce warm light (in the red, orange, and yellow spectrum). Those with a high color temperature produce cool light (in blue and white spectrum).
Our food safe fixtures are 5000K and provide bright high quality lighting for your indoor areas.
5. Light Quality: Color Rendering Index
Where food's handled, the light fixtures must have a very high color rendering index. The FDA and USDA require general food processing lights have at least a 70 CRI.
LEDs have a higher color rendering index than traditional lighting systems. This plays a crucial role in enhancing visibility and mitigating risk. Defects in food become easier to spot and misplaced objects are easier to find.
In food processing environments, proper color rendering is vital for assuring product quality. A high CRI is also crucial for compliance as it is one of the things food safety inspectors look at.
6. Beam Angles: Proper Light Distribution
The beam angle is what determines the distribution of light. A wide beam angle produces softer light and distributes it better to different areas of a room.
A narrow beam angle produces concentrated light good for accent lighting. It makes the light more intense and focused.
Our LED food safe lights are available in a range of beam angles: from 50° (narrow) to 120° (wide).
Beam Angle Selection
Ask us to run a lighting photometric to determine the perfect light and beam angle for your indoor space. Look at both the foot candle measurements and max/min ratios to make sure your space is bright and uniform.
NSF Certified Food Safe LED Lights
1. Be easy to clean. This decreases the risk of contamination. It also lower lighting maintenance costs and downtime with their long lifespans.
2. Be bright enough to enhance visibility for employees in the facility. The light should not cause blinding glare or cast shadows which may be the cause of accidents.
3. Meet all the government and industry regulations relating to food quality and safety.
For the longest time, food processing facilities used old lighting technologies. These include sodium lamps, metal halide lamps, xenon lamp, and fluorescent lights. But these lighting systems have many limitations. They have spectral power distribution and emit a lot of heat. In food processing plants, very high temperatures can affect food processes. Some add HVAC systems to offset heat created by these lights. This increases energy consumption.
Most old lighting technologies contain mercury. Disposal of bulbs that contain mercury must happen in a specific way in case they break.
Metal halide lamps and fluorescent buzz and flicker if they operate for long hours. Buzzing and flickering light can interfere with the productivity of employees. They can also cause eye strain and headaches.
LED lights emit very little heat. Their efficiency gets better at lower temperatures and they work best in cold places.
Lighting Standards in the Food and Beverage Industry
Food processing plants have the highest standards of sanitation protocols and cleanliness. They undergo stringent inspections. The National Sanitation Foundation International (NSF International) has stringent compliance standards. They look at a facility’s condition and the degree of contact with food, direct or indirect contact.
The foundation classifies equipment used in food processing environments into three zones:
1. Splash Zone
In this area, direct contact with food isn't expected. Liquids used for cleaning can splash or spill on the fixtures surfaces. In splash zones, high-pressure hose wash-downs occur. Splash zones include damp or wet process areas. These are areas that use hose wash-downs, and high-pressure purging or decontamination areas.
2. Non-food Zone
In this zone there isn't any direct contact with food under normal working conditions. The light fixtures used are not exposed to wash-downs or splashes. They have to be well protected against dirt, debris and cleaning solvents. Non food zones include food storage areas, dry and damp process areas, and kitchens.
3. Food Zone
According to NSF International regulations, light fixtures must have IP65 or higher ratings. The lights must have UL or ETL Listing for damp and wet locations. In hazardous locations, use vapor-tight, clean-room rated lighting fixtures.
On mistake food processing facilities make is to use common industrial light fixtures. Lighting fixtures used in food processing facilities must work in sanitary conditions.
The lighting fixtures used must follow the regulations set by NSF International. They depend on the environment of a particular area. There are usually different environments in one food processing plant. Each environment has its own lighting requirements.
How LED Lighting Greatly Impacts Food Safety
To enhance safety and productivity, the food industry relies on powerful lighting systems. This is why food processing facilities are switching from conventional lighting to LED. LED lighting complies with the stringent regulations that are set by the FDA and the USDA.
The adoption of LED in the food and beverage industry will reach $80 billion yearly by 2020. Food processing and manufacturing plants are leading the rest in the adoption of LED. LEDs offer great solutions to then complex and challenging conditions of these environments.
LEDs can help decrease thermal damage and degradation of food. They are perfect for cold storage applications. Research shows that in post harvest, LEDs preserves and enhances foods nutritive qualities. They also lower fungal infections. LEDs paired with photo sensitizers or catalysts can make pathogenic bacteria in food inactive. This helps preserve the freshness of foods in the post harvest stage.
Since LEDs are solid state, they are devoid of fragile parts and glass. Dangerous chemicals and parts cannot escape and contaminate food. LEDs also give off very little heat. This means cooking processes are not affected by higher temperatures caused by lighting. Slight changes in temperature can melt foods like chocolate, icing and cake batters.
Food Processing Facilities Require Bright Lighting Solutions
The amount of light needed for food processing depends on the activities that take place. The more crucial the operation in safeguarding food, the higher the light level. In food processing areas where work's done with grinders, knives and saws, a minimum of 55 Foot Candles (FC) are required.
In areas where inspection on products occur, 110 FC's specified. Less intense light is required for less crucial areas. Walk-in refrigerators, receiving areas, restrooms, storage areas, and locker rooms need less FC's. The light must always be enough so operations get executed safely and efficiently.
