How to Choose an LED for Lighting

LED (Light-emitting diode) bulbs are commonly used for lighting due to their impressive lifespan and cost-effectiveness compared to incandescent bulbs. They are also more environmentally friendly and energy saving than conventional bulbs. Manufacturers have made great advancement in the manufacture of LED light bulbs over the years by making it possible to produce white LED light using a single semi-conductor chip as opposed to prior years where the same could only be produced through mixing three different chips. This has led to greater efficiency and reduced cost of these bulbs. When choosing an LED light, there are various things that you need to consider. These include the following. Features of LED light bulbs When buying LED light bulbs, there are various terms that one is accustomed to that are used to define the efficiency and performance of the bulb. It is important to understand them when purchasing LED for lighting in order to get highly efficient bulbs. These include the following. Watts. Watts or wattage refers to a measure of how much energy a light bulb draws, as opposed to the belief that it is the measure of brightness. With LED light bulbs, watts are not an indicator of the bulb’s brightness, since they draw less energy compared to incandescent and traditional bulbs. Lumen (lm). This is the measurement of the brightness produced by an LED bulb and is what you should look out for when purchasing a light bulb. A bulb with higher lumens will burn brighter; therefore, get a sense of the level of brightness you want before purchase. You can always have the bulb tested for this. Color of light bulb One latest feature of LEDs is that the light can be adjusted to the full spectrum of colors. Some manufacturers have designed LED bulbs that can be controlled through a smart phone allowing one to choose the desired color of light from a full palette. The color factor is an important consideration when choosing these bulbs. The color will depend on the room where it is used and the desired mood to be created. Yellow and white lights are common; however, other colors such as purple and red are also available. They range from soft to warm and bright lights. Type of dimming switch In some cases, LED bulbs may not be compatible with traditional dimming switches. You may need to have the switch replaced or get […]

Understanding NiHM and Li-ion Batteries

Most people know that they need camera batteries for their camera to function. However, with the numerous features that modern digital cameras come with, battery run times keep decreasing. Some of the features that deplete battery charge include the liquid crystal displays, the camera’s image storing system, the flash, the exposure system and more. The moment your camera starts to behave sluggishly, chances are you need to replace or recharge your camera batteries before they completely run out. Here are some of the different camera batteries you could find in the market if you are looking to purchase new ones. NiMH camera batteries These are the most common option for people who require rechargeable AA batteries for their camera. One of the greatest advantages of these batteries is that they are non-toxic. This makes them an environmentally friendly option. Additionally, since they are rechargeable, you will not be throwing them out and replacing them, thus reducing your impact on the environment. Although the purchase price of these batteries may seem a bit high, they are actually a good investment, because, as aforementioned, you will not have to keep buying batteries. However, it should be noted that the more charge and discharge cycles that they have, the less charge they will be able to sustain. As such, with extended use they will eventually have to be replaced. It should be noted that to keep you rechargeable camera batteries at optimum, you should only charge them after they have completely run out of power rather than recharging them on a regular basis. This is because topping off the charge heats the chemicals that are found in the rechargeable batteries casing. This eventually causes the reduction in their longevity. Li-ion camera batteries Li-ion refers to batteries composed of lithium ion. These are commonly referred to as battery packs and are the main source of power in an array of modern digital cameras. These battery packs are rechargeable and will have a case they are secured to for direct recharging from a power socket. Lithium ion camera batteries are also preferred due to their long shelf life, meaning you do not have to keep purchasing batteries for your camera. However, it should be noted that these batteries also pose a risk of leaking especially if not stored in a cool and dry place. As such, if you are not using your camera, it is […]
