LED replacement bulbs are durable and ecologically friendly. Did you know you can recycle LED bulbs and reduce your carbon footprint up to one third? LEDs outlast the competition, staying bright for up to 11 years of continuous operation. This means less time climbing ladders trying to replace those hard to reach bulbs in vaulted ceilings.

UV radiation affects the human body. Skin and eyes are affected. There UV radiation can cause numerous health problems - in the worst case skin cancer. The number of skin cancer cases continues to rise in Germany - and worldwide. In Germany, the number of new skin cancer cases doubles every 10 to 15 years.

Ultraviolet (UV) radiation can cause lasting damage to our skin. With this in mind, readers are strongly advised above all to avoid intense UV radiation and to wear suitable clothing when spending time outdoors. Any skin that still remains uncovered should be protected using sun cream.

The best way to protect yourself from UV-damage outdoors is to cover up accordingly. Every piece of clothing will protect you from acute ultraviolet (UV-) radiation. The degree of protection provided by clothing primarily depends on the fabric type and density. The rule of thumb is the denser woven, the better protected. Even special UV-protective clothing is offered today.

How beautiful it is when the sun shines! However, sun protection is indispensable because solar radiation involves not only positive effects on the body and wellbeing, but also dangers to health from the ultraviolet (UV) radiation contained in sunlight.

Anyone who spends time outdoors knows that they have to protect themselves from the sun. But what about in the car? Do car windows protect against UV radiation?

LED light bulbs can save you money not only because they are roughly 80 percent more energy efficient than other bulbs, they also produce far less heat than metal halides, CFLs, and incandescent light bulbs. Upgrading to LED lighting means you won't spend your summer months cooling down rooms that your light bulbs are busy heating up. While originally a cooler blue tone than incandescent bulbs, LEDs now come in daylight and warm white color temperatures so you can more easily replace your existing bulbs without altering the color of your room. Visit our Lighting Guide to see what difference color temperature makes. LED lighting also offers a superior color rendering index (CRI), so you can see the colors of your artwork or makeup more accurately.

LED light bulbs for the win! When it comes to purchasing energy-efficient lighting, LEDs surpass CFLs by a wide margin. LEDs are instant-start with no warmup time needed. They work well in cold weather, and are substantially more durable since manufactured out of plastic instead of glass. From standard bulbs to fluorescent tubes, LEDs can replicate the same lighting conditions found in fluorescents while lasting longer and using less energy. As an added bonus, all LEDs are RoHS compliant and do not use mercury, a claim that can't be made by fluorescent bulbs.

Ultraviolet (UV-) radiation can cause permanent damage to both the skin and eyes. It is therefore strongly recommended not only to observe the sun protection rules but also to effectively protect the eyes from the sun.

In principle, skin that has not been exposed to the sun for a long time should always be slowly accustomed to prolonged sun exposure. Stay in the shade for the first few days. Avoid sunburn at any rate! The best way to achieve this is to use sun protection measures that correspond to your skin type, and to observe the sun protection rules.

Equivalent Wattage - While lumens are the new standard, it helps to have an easily recognizable guide. Comparing an LED bulb to an incandescent will give you a rough estimate of just how well it will light a room. As a very ballpark figure for LED wattages, 1/4 or 1/5 the incandescent wattage value is usually close to what you need. Lumens - Lumens directly measure just how much light the bulb gives out in total. On average, a 60-watt incandescent shines at 800 lumens, with roughly 50-100 lumens of difference above or below. The variance depends on manufacturer and age of the lamp. LEDs are directly rated for their max lumen rating and last much longer without dimming of the bulb. Color Temperature - Your guide to how the light itself will look. Lower values are warmer, with 2700-3000K being a more incandescent "warm white" while higher temperatures like 5000K will deliver a very harsh "stark white" light. Our Lighting Guide lets you select a color temperature and see how it transforms a kitchen. Driver Content - Because of their design, LEDs do not typically run on AC voltage. Many LEDs require some form of driver to convert the voltage from AC to DC for proper operation. The majority of socket-based LED lamps are self-driven, but you should always check before buying to make sure that you buy both an LED and a driver at the same time if it isn't self-driven.
