When it comes to lighting areas where color accuracy is crucial, such as portrait studios, retail stores, hospitals, medical and commercial offices, display cases, and warehouses, a high color-rendering index (CRI) is key. CRI refers to how accurately a light source reveals the true colors of objects, people, and surroundings and involves a distinct testing method with comparisons to incandescent light or daylight.

The spectral graph below can be helpful in understanding the advantage of high-CRI light sources. Lights with a low CRI will show fewer colors while high-CRI lights cover more of the spectrum. A light source’s ability to show more colors increases its accuracy in revealing the true colors of people, objects, and surroundings.

can light, linear light, or other high-CRI bulb or fixture. Lights with a CRI of 80 or higher are considered to show colors most accurately. The photo below shows how different CRIs can affect colors and skin tone.

Many older homes have old wiring systems and obsolete switchboards and fuse boxes. These have very poor functioning and are unable to provide proper supply to the type of devices that are used in the home today. Over the last few decades there has been significant advancement in circuit breaker technology and many people are now proactively getting these old ceramic fuse boxes replaced with current-day circuit breakers.

However, as mentioned earlier, there are some older homes that still have these re-wireable fuses. This is largely because people aren’t aware of the dangers these fuse installations pose. Those who have heard it’s important to upgrade to circuit breakers feel that it’s just something people do because their electrical contractors tell them they should.

The rationalisation they have for it is that when they haven’t faced any issues with it for so many decades, there must be nothing wrong with it. They feel it’s just a way in which electrical companies make some money by telling their clients this and getting them to upgrade to newer systems. They couldn’t be further from the truth. Here is a list of all the dangers associated with re-wireable fuses:

Most people, electricians or otherwise, tend to use regular copper wires to replace the melted fuse wire. They aren’t really aware that a fuse wire is different from a common copper wire and that the latter isn’t designed to take the load of the circuit. In many ways, this inappropriate replacement in itself is a problem. And when the fuse blows again, they simply take another wire and replace the older one.

What they fail to realise is that fuse wires generally have very low melting points. Contrastingly, normal copper wires have a very high melting point. In addition, it’s not possible to standardise the current carrying capacity of these wires as that depends on how they have been positioned inside the base and the fuse carrier.

As you can see, re-wireable fuses are a distinct danger and this is something that shouldn’t be taken lightly. It’s best not to wait till a catastrophe occurs. Simply call Allround Electrical for an evaluation of the electrical installations and the old fuse box in your home. We will provide objective advice and a reasonable quote for replacing the re-wireable fuses in your home. The number to call is 1300 169 263.
