When to… when not to

There is little doubt that the global drumming of awareness to reduce carbon emission has began to see some positive results. Consumers these days are looking out to replace conventional lighting with LED luminaries. However, there still is an element of disillusion, because many fall off the chairs when they learn of the implementation costs.

Just as when fluorescent was first introduced into the market, the initial cost was quite a deterrent for many, but over time, as the production & supplies reach all shores on the atlas, the unit costs trickled down.

Just as when high discharge lamps were first introduced, the bell curve for the implementation costs also saw a decline when market adaption took place.

Therefore in the same fashion, we can expect the costs for LED to decline at some point when more of the market seeks to adopt & implement. Besides, LED lighting can be categorized as electronics, and like all gadgets in the market, the costs can be moderated further as more variants flood the market.

To clear the air a little bit more with regard to the misconception of LED lighting. When to, or when not to use LED lighting? Factually, there’s no limit as to when/ where to apply LED illumination. However, the question of breakeven & returns-on-investments (ROI), beckons. In short, the shorter the time taken to breakeven, the sooner you gain ROI.

For commercial & industrial markets, where operation hours can span from 12 to 24hrs daily; implementing LED lighting is undoubtedly ideal. Not to mention, the longer the LED lighting runs (with good heat dissipation) can serve to optimize the performance lifespan of the lamps. Though implementation costs can be quite steep, given the immense reduction in operation costs, the breakeven point can be benchmarked at approximately 24-30 months.

Likewise in amenities, public parks, public buildings & facades, where average operating hours span from 5 to 12hrs nightly, the breakeven point can be benchmarked  at approximately 40-60 months.

In cases of private residential application, where nightly operation may or may not exceed 5hours, the breakeven point may only be realized somewhere >60 months. Hence, home owners are often caught off guard, and resort to using cheaper alternatives for LED lamps. Given the circumstance of application, may not serve to achieve optimum performance & lifespan of the investment.

Like all electronic appliances/gadgets, the optimum lifespan/performance of LED lamps can be achieved, only if, they are operating over a steady span of duration. Ie: several hours per run. One can expect the lifespan to be drastically shortened if it is being turned on & off frequently, likened to starting/stalling/stopping the engines of any mechanism.

Meanwhile, be reminded that the daily power consumption from lighting is significantly tiny when weighted against the use of your; air-conditioning/ refrigerator/ washing-machine/ iron/ water heater/ convection stove/ electric over etc.

So, we should act responsibly towards the daily power consumption in an entirety, and not paying attention to things that consume the least.
