If you’ve got questions about LED floodlights then you’ve come to the right place, because today we’ll answer five common questions about LED floodlights.

Question #1: Are LED floodlights ‘worth it’?

You might be wondering if it’s worth investing in LED floodlights. Well, there are five main benefits to be had from LED floodlighting:

Benefit 1: They’re cost effective

If you’re upgrading from halogen floodlights to LED floodlights, the initial cost will be more. However, they consume up to 90% less energy than their halogen counterparts, meaning your electricity consumption will be a lot lower, saving you money in the long-run.

Benefit 2: They last longer. A lot longer!

LED floodlights are longer-lasting than halogen floodlights. In fact, they’ll last up 30,000 hours, which is 20-times longer than your average halogen flood, saving you yet more money.

Benefit 3: They have a much cooler running temperature

Halogen floods can get hot to touch. LED floods come with metal heatsinks that direct heat away to maintain a lower running temperature. This also helps prolong the lifespan of the LED chips inside.

Benefit 4: They have wide beam angles for better coverage and security

Whether you’re lighting-up a car park, a garage or your back garden, LED floodlights are guaranteed to give you a wide beam angle that offers greater and more efficient coverage for better security.

Benefit 5: They are designed to perform, whatever the conditions

LUMiLife LED floodlights come with waterproof and dustproof IP65 casings, so you can expect the same high-quality performance, whatever the weather or working environment.

Question #2: Are LED floodlights as bright as halogen?

As we briefly explained before, LED floodlights consume far fewer Watts than their halogen counterparts – so they use a lot less energy. But does this mean they’re not as bright? In short: No. You can expect the same level of brightness from an LED floodlight as a halogen floodlight. Brightness isn’t measured in Watts. It’s actually measured in lumens. Always look for lumens when replacing a halogen light with an LED alternative. For example, our 30W slimline LED floodlight beams lumens of light –equivalent to a 100W halogen floodlight, while consuming a lot less energy. In fact, if we think of brightness in terms of ‘lumens per Watt’, then LED floodlights are considerably brighter than their halogen alternatives!

Question #3: Can LED floodlights be dimmed?

Some LED floodlights are dimmable, but not all. If you require a dimmable LED floodlight make sure you check the product specification for a dimmable feature. If the technology required to dim an LED floodlight has not been built into the product, then you won’t be able to dim it.

Question #4: How do you choose LED floodlights?

So, you’re ready to buy, but you’re not quite sure what you need? Well, ensure you cover the following four areas to get everything you need from your new LED floodlights. Brightness: This all depends on where you’re going to use the floodlight and for what purpose. If you’re using it for a little extra safety or security in your driveway, then a 10W or 30W LED floodlight, which beam 910 lumens and 2,750 lumens respectively, will probably do the job. For larger areas, such as car parks, you’ll need a high-performing 200W LED floodlight that beams out a huge 23,000 lumens. Additional automatic capabilities: You then need to decide if you want an LED floodlight with additional security and efficiency options, such as a distance sensor, automatic time-mode or daylight sensor. A distance sensor tells the floodlight to switch on automatically when motion is sensed within a certain distance of the light. The time mode determines how long the LED floodlight remains on after it turns on. Finally, the daylight sensor programmes the light to either only come-on through the day or at night. Colour options: LED floodlights are able to cast different shades of white light. At LED Hut, we offer warm white and cool white colour options. Warm white casts a more welcoming tone, while cool white offers greater exposure and is best for security lighting or task lighting. Design: If you’re short on space, design is really important. Keep an eye-out for slimline models that can be placed anywhere without compromise. They are just as powerful as their bulkier alternatives, and selected models also come with 360 degree brackets that allow for greater versatility when installing.

Question #5: How do LED floodlights work?

LED floodlights use light emitting diodes (LEDs) to generate light. LEDs in floodlights are semi-conductors that turn electricity into light by passing the electric current between two leads (metal pads called SMDs). When the required level of wattage between the leads is reached, energy is released in the form of photons, which provide the light. Whereas traditional floodlights use heat to generate light, LEDs don’t, which is why they consume such a low amount of electricity by comparison. They also remain cooler to touch, because heat is not required to generate the light, and heatsinks are used to reduce wasted heat energy, which improves both the efficiency and the lifespan of the floodlight. We hope that you've now got all of the information you need to make an informed purchase. If you have any questions we haven't covered here just ask in the comments below.

LED lights have been around for a while but are still relatively new to a lot of people. To help you get started, we've answered ten of the most common questions about LED lighting.

1. How do LED lights work?

LED (light-emitting diode) light sources work differently to traditional lighting sources, such as incandescent. Incandescent bulbs work with a burning filament at the centre of the bulb that eventually burns out. LEDs derive their light energy from electrons that move within a semiconductor material. When a voltage is applied to the leads these electrons are stimulated to create light-based energy. LEDs aren't just used for lighting either, and can be found across a wide range of electricals. For example, you can now get LED TVs that produce a better picture quality and allow for slimmer designs.

2. Are LED lights safe?

As with any electrical fitting, you need to take obvious precautions during the installation process. If you're re-wiring directly to the mains, then we always advise that you contact a qualified electrician. And, as with any source of light, it's advised you don't stare directly at them, otherwise you'll run the risk of causing damage to your eyes. However, when installed, LEDs are actually safer than older light sources such as incandescent and halogen. This is because they are fitted with heat sinks that dissipate heat away – so you're less likely to burn your fingers upon contact, unlike with traditional lighting sources that are dangerous to touch.

3. Are LED lights dimmable?

Yes they are – but you have to make sure you purchase a dimmable LED bulb. You can't just dim a standard LED bulb. You also need to make sure you have a compatible dimmer switch. If you're upgrading from incandescent or halogen to LED, it's more than likely you're currently using a leading-edge dimmer, and these aren't compatible with LED. We advise upgrading to a specialised LED dimmer, such as an LED-ready trailing-edge dimmer, that'll deliver the best performance while prolonging the lifespan of the bulb itself.

4. Are LED lights cheaper to run?

Yes, LED lights are significantly cheaper to run because they consume less energy. While they'll cost you more up-front, you'll recoup that initial investment in a matter of months, then continue to save every month after.

5. How do LED lights save you money?

There are two key ways in which LED lights save you literally hundreds – if not thousands – during their lifetime. • Cost to run. LEDs use up to 90% less energy than incandescent and halogen light bulbs, which are the most commonly-used light bulbs around. This means that when you make a switch from an older light source to LED, you'll quickly start seeing your energy bills plummet. In fact, you'll make back your initial outlay in a matter of months and continue saving thereafter. It literally pays to switch to LED! • Lifespan. Incandescent and halogen light bulbs are made to last just 2,000 hours. LEDs, in comparison, are made to last up to 25,000 hours. Based on average use, that’s a whopping 15 years of service. So not only will you see those energy bills dwindle, you'll save money on replacements too.

6. What causes LED lights to flicker?

As with any light source, LEDs can flicker – particularly if they haven't been installed properly in the first place. One of the main reasons behind LEDs flickering is the power supply they're receiving. While older light sources require an AC power supply, LED bulbs require a DC power supply. That's why it's so important to have an LED driver that converts your power supply from AC to DC. This will ensure there's a constant supply of power to your LEDs to combat any flickering. Most LED bulbs have the driver built into them, but certain types of LED lighting require a separate driver to power them. Simply check before you buy.

7. How do LED lights help the environment?

LED's consume very little energy, particularly when compared to halogen and incandescent equivalents. You can replace a 100W incandescent bulb with a 10W LED and still enjoy the same level of light output, while reducing greenhouse gas emissions. Plus, LEDs don’t contain toxic chemicals such as mercury, unlike fluorescent lights that contaminate the environment when disposed of. Finally, LEDs last up to 20-times longer than any other traditional form of lighting, reducing the number of replacements you need and further lowering your impact on the environment.

8. Do LED lights get hot?

You can expect a little bit of warmth radiating from your LED lamp – but a lot less than halogen and incandescent equivalents. This is because LEDs use 90-95% of their energy supply to produce light, while the other 5-10% of energy used produces heat – the opposite being true for older bulbs, which is why you have to careful when changing them.

9. Are LED lights good for growing plants?

They are indeed. You can now get LED hydroponic lamps that help stimulate plant growth by providing the optimum amount of light wavelength and intensity required for different growth phases, but without the inefficiency that comes with CFL and incandescent grow lamps.

10. Are LED lights bad for your eyes?

As with any source of light, we strongly advise that you don’t stare directly at LED lights as they could subsequently cause eye damage. Apart from that, no, they’re not bad for your eyes! If you're ready to make the switch you can find all of our LED lights here.
