Reviewed: Solar-Powered LED Security Light

When North American online retailer Deelat contacted me a few weeks ago about reviewing one of their products – I jumped at the chance.

They asked me if I’d like review one of their solar-powered LED security lights. I immediately said yes, as I’ve always been fascinated by solar-powered lights (but frequently disappointed by their performance.)

Despite my UK location, Deelat arranged for the product to be shipped to me by FedEx. It arrived promptly, just five days after being sent from Canada.

Let There Be Light! Here’s How to Pick the Best Lightbulb

As regular readers of Eco Tech Daily will know, I’ve been fascinated by the rapid transformation of lightbulbs in recent years. (Please see my article 2015: The Year of the LED).

Not so long ago, consumers had only three options when choosing a lightbulb.

The traditional incandescent lightbulb. Which offered warm light, but suffered from short lifetimes and expensive running costs.

The halogen lightbulb. This improved on the technology used by incandescents, and offered smaller bulbs with high-intensity light. Halogen lightbulbs also had better energy-efficiency (i.e., were cheaper to run) than incandescents.

2015: The Year of the LED

If there is one technology that is likely to trend in 2015, then it is LEDs.

LEDs, or Light Emitting Diodes, have been around for many decades.

However, recent years have seen both a huge reduction in manufacturing costs of LEDs, and impressive enhancements to their lighting output.

While early LEDs were first seen in pocket calculators and watches, they are now cheap and powerful enough to begin replacing existing lighting – and even to create new lighting options.
