To support visual acuity by setting a threshold for adequate light levels and requiring luminance to be balanced within and across indoor spaces.

ANSI/IES RP-1-12 provides recommended luminance ratios for offices. It notes that studies suggest that ratios do not exceed 10:1 or 1:10 between a task and a remote surface.

The Dining Services Ergonomic Design Guidelines recommends lighting levels between 70 and 100 foot candles in warewashing areas for the safety and wellbeing of foodservice employees.

ANSI/IES RP-1-12 provides Table B1 for recommended maintained illuminance targets for the horizontal plane. Table B1h recommends a target value of 150 lux for cafeterias.

ANSI/IES RP-1-12 provides Table B1 for recommended maintained illuminance targets for the horizontal plane. Table B1h recommends a target value of 30 lux for fine dining.

Adequate light levels are needed for a broad variety of activities, including reading various qualities and types of print, and working on detail-oriented tasks. Brightness levels also contribute to the perception of spaciousness, as well as to the overall visual appeal of illuminated spaces. Targeted task lighting can provide the necessary amount of light at workspaces without over-illuminating ancillary spaces; ambient light levels of 300 lux are sufficient for most tasks. Pairing adjustable direct task lighting with indirect or diffuse ambient lighting allows user customization and good visual acuity while providing more suitable background light. Light intensity for visual acuity is measured in lux (or foot candles), which is a measure of the way the eye responds to light weighted to the response of the cone cells—the main photoreceptors for daytime vision, located on the retina of the human eye.

Not only are the staff unhelpful but rude as well. Was told the lights I wanted were out of stock and in order to bring my lights in I’d have to pay a deposit. Was told lights would be there in 2 days, I called THREE times on the day they were due and was told “give me your number I’ll call you back”. I received no call back. The third call I was finally told they were back ordered at the warehouse and they’d be in the following week. After explaining the electrician was booked and I couldn’t wait I was told I could pick them up at the warehouse (I thought they were backordered?!?). Fine, went to the warehouse to get them and the warehouse said the store never called, never ordered them and they had plenty in stock plus they make regular deliveries to the store. I had to call the store to make the balance payment before the warehouse would release them and as I’m paying for the privilege of picking up my own lights I explain to the sales associate that the warehouse never received the order. The sales girl told me I was rude after being caught in her story ( L I E) of being backordered . They also told me that they had a full refund policy but the website clearly says they only offer store credit. I try to give business to smaller local stores whenever possible but with staff, policies and drama like this with no “head office” to answer to it makes it hard to trust small business owners.

I have purchased over $1400 worth of chandelier's, lights and lamps for my new house from Ultra Lightning. It took me some time to finish installing them. When the certified electricians from Bona Electric did an install, it appeared that the employees from Ultra Lighting have sold me broken bathroom chandelier. When I brought in the lamp for service, they have informed that they can't give me a cash refund, and that they will send the product to the manufacturer for service. Around 2 weeks passed and I got a phone call from the sales person informing me that that I have to pay additional $100 for service the faulty product which they sold. Furthermore the account manager charged me for a box of light bulbs which to this day I haven't received.

Found the same lighting in Cambridge 25% cheaper and they spent the time with me to help me come up with another option to make the glass pendants work. Cambridge said if I had purchased with them and it didn't work, they would have sent it back NO CHARGE to me AND given me a credit!

We ordered a 24 light chandelier and 8 additional the same style mini pendants from Mississauga location. The big light fixture was ok, but small pendants were defective 0,5" smaller than stated on the website. We returned them to the store to exchange for new pendants the same style but a little bit bigger. First they said the new pendants will arrive in a week, then they said they are backordered and will be only in 9 weeks . We could not wait so long and asked for a refund. They were simply rude, just ignored everything we said. No refund. Stay away from this place!Horrible customer service, attitude, horrible policy. Never ever.

ANSI/IES RP-1-12 provides recommended luminance ratios for offices. It notes that for ceiling luminance ratios, 10:1 is the maximum acceptable ratio.

Sold me lighting for $1200 that would not work even after spending lots of time showing the salesman pictures of the lighting location. Refused to give me a refund even though they took my $ before telling me about the no refund policy, then demanded a 25% restocking charge PLUS shipping to return product they sold me that was incorrect and would only give me a store credit. The owner hung up on me numerous times. The worst experience I've ever had! Do NOT buy here!!!

The worst and unacceptable customer service. Buyers be aware. Very nice when selling the products only. Bought Crystal $1,000 chendelier and couldn't turn the light off. After making few trips to the store and returning chandelier received a store credit which was never recognized. Beginning of December went with the store credit, placed an order for another Chandelier. I was told that it will arrive within 2 - 3 weeks and definitely we will receive it before Christmas. I left store peacefully and started driving. All of a sudden, store clerk started to run against my car screaming and hitting my side car window that my order will never be placed. I was very scared. Half a year and issue is still not resolved.

ANSI/IES RP-1-12 provides Table B1 for recommended maintained illuminance targets for the horizontal plane. Table B1h recommends a target value of 100 lux for casual dining and 200 lux for fast food dining.

The vanity light I ordered never arrived when promised. They refused to return my deposit so I could buy another light quickly before my contractor left. The light fixture finally arrived 4 days later. The company refused to compensate me for all the inconvenience caused by the late delivery and insisted I pay the small outstanding balance of $41. Shame on Ultra Lighting for their atrocious customer service. I would never order a light fixture from them again!

After looking everywhere for just the right dining light to go with our new dining table, we came across Ultra Lighting by complete accident, while walking around Queen W. While the store on Spadina has only recently opened, Ultra Lighting has been around for a while, having recently moved from their old Church Street location. Not only were my wife and I impressed with the range of modern fixtures that the store had, but also by the great prices we found. Another pleasant surprise was the great service we found at the store. Each time we've gone in, we've never felt pressured to buy. Also the owners are also very helpful in providing great advice to assist with each purchase. Our new dining light has transformed our dining room and goes perfectly with our table!

The Ontario Ministry of Labour's "Computer Ergonomics: Workstation Layout and Lighting" provides a checklist for computer workstations, which includes checking that light levels fall within 300-500 lux, and also that task lights are provided if required.

I had renovated my condo and replaced all the old lighting to make it ultra modern and got an amazing lighting consult from Bryan. He truly has an amazing eye to suggest the best lighting for each space. My place looks stunning. All my special orders came in as expected. Its been over a year and no issues. I would highly recommend this store, especially with lighting consult.

Horrible Service, in particular from Brian the so called owner. He told me he would take a fixture back, but when his fellow worker Mohan knew about this-he did not approve and Brian went back on his word and gave me a story full of BS. Prima lighting in vaughn MUCH better. Do not go here, you will regret it. Not many fixture options, horrible customer service, and an owner that does not keep his word to the customers. Save yourself the grief and go somewhere else.
