At M-Elec we are not only committed to producing innovative products that are easy to fit and reasonably prices, but we also make a big deal about the quality of our products. How do we do this? The products that arrive to our Qld warehouse are consistently tested by Quality Control department so we can assure our quality is maintained. The new products undergo a very thorough examination, to make 100% sure all the standards and procedures are followed. Today we are going to introduce you to the “spot checking” process which is for the quality control of established products. Our knowledgeable Quality Control department chief Blake Jarvis is going to take us through the process of testing 1boxD10 downlights.

Unloading the new products and bringing them in the warehouse

When the products arrive to the warehouse they are unloaded from container, counted and processed. Testing is normally performed on a variable percentage of the incoming stock. If there are irregularities found, the testing sample increases. The first thing to be checked is the product packaging. All the technical data of the product and declarations must be verified and should be consistent with the technical data on the spec sheets supplied with the product. Some of the products need to have special stickers on the packaging such as the white trim sticker for the MR10. Once the package is opened, the product is thoroughly examined for flaws, breakages or inconsistencies. Then the technical data on the product itself is checked; IC-F stickers, made in China declaration, RCM stamp, model number & the technical specification. If there is a power driver supplied with the product, all the same things need to be checked plus the current data, voltage, switching and the wiring diagram. The wires, cable and plug also need to be checked for conformity. Another thing that is as equally important is the colour of the trim which must be compared to existing samples.

Checking the driver – Variac testing – dimming testing

Once the first phase of testing is done, we proceed to colour output testing. A special device called variable AC transformer or Variac is used, which defines how many volts are going into the driver. There is always a declared allowed voltage printed on each driver, so the Variac supplies different voltages to see how the lights respond. A few lights are connected at the same time for this testing and checked one against each other. All the colour outputs should be the same and when the 1-Box or other multi-temperature technology is involved we test that the colour selection functions are working correctly and evenly.

Recording the results

The second set of tests uses several different dimmers to see how the lights react when dimmed. Dimmers from brands like Clipsal, Cabac and Diginet, which work well with our dimmable LED products, are often popular choices among customers so we test several models to ensure that multiple fittings will dim evenly. Of course if the light is not dimmable this test does not need to be done. We do find that, with such a broad range of dimmers available to customers, the results can vary from product to product so we recommend that installers perform a quick on-site test of dimmers prior to installation. This will ensure that a suitable dimmer is selected to achieve the desired dimming performance.

When testing high voltage lights such as battens the earthing and active to earth test need to be done as well. At the end the lights are turned on for 20 minutes to see if they function properly.

Green doting – testing completed

When the quality control testing is done the box gets a green sticker, so the products are good to go.
