Myth 29: 

LED lights are too expensive

 

Any technology at an early development stage is usually a costly investment. So, the question should really be: Expensive compared to what? Lighting has evolved tremendously within the past century. Since the introduction of LED back in the 1980s, the technology behind LED has evolved enormously and consequent cost of this technology has dropped significantly as well. When evaluating the price of LED products, we need a meaningful way to measure cost/benefit. There are many choices in the marketplace and when comparing the prices of the various LED bulbs one of the key performance attribute benchmarks is lumens.

Lumens: Wattage used to be the standard method of calculating a lamp’s brightness, however since LED technology has become more efficient, this measure is no longer as relevant as it once was. Newer LED lamps consume less watts without compromising light output. Today lumens are the most accurate measure of the brightness of a light source.

So, when you are comparing lamps (bulbs) look for the number of lumens, and secondly, the lifespan cycle. To put it into perspective, here is a quick comparative chart:

Result: FALSE! LEDs help you save money.

Myth 13 LEDs contain mercury EN

Myth 13: 

LED contains mercury

An excuse we sometimes hear from consumers for not switching to LED technology is that LED lamps contain mercury, thus they are not safe. Actually, the truth couldn’t be any further from the statement. In fact, LED based products do not have any mercury. They do contain a few soldering spots of lead and/or arsenic but this is not in any powder form and they are very minimal within the product. Therefore, no components of LED lamps and products are hazardous to health.

Now, if you are really worried about mercury levels, be aware that CFL lamps (compact fluorescent lamps) do have mercury in a powder form. Thus, if you drop and break a CFL lamp, the powder could be released into the air and there would be a danger of breathing it in.

Keep in mind that for any electronic device, there are designated drop-off points to discard the materials, so we do encourage you to dispose wisely. 

Here is a link from Government of Canada about the safety of these type of lamps:

Myth 06 image

Myth 06:

Lighting only represents a little portion of my electricity bill.

Hydro Quebec's illustration sums up the average breakdown of electricity consumption in Quebec. Therefore, we can estimate that in Quebec, 5% of the costs of the electricity bill relate to actual lighting consumption. Although this may be your case as a Quebec resident, other locations in Canada or even across the border can rapidly increase to 15%.

So, in part, it is true… But what is not being taken in consideration, are the costs related to the maintenance of the equipment (lamps or bulbs and luminaires) and the frequency of their replacement. Are you having an “AHAA!” moment?

LED lamps and luminaires have a long lifespan and very low energy consumption. So, opting for this technology represents short-term and long-term consumer savings that can represent a few hundred dollars of savings even in the first year!

Now if you are a retailer or are in the industrial market, this consumption rate is much greater. Which is why many government establishments offer allocations for converting to LED.
