LEDs are available in a wide variety of sizes and shapes. The 'standard' LED has a round cross-section of 5mm diameter and this is probably the best type for general use, but 3mm round LEDs are also popular.   Round cross-section LEDs are frequently used and they are very easy to install on boxes by drilling a hole of the LED diameter, adding a spot of glue will help to hold the LED if necessary. LED clips are also available to secure LEDs in holes. Other cross-section shapes include square, rectangular and triangular.   As well as a variety of colours, sizes and shapes, LEDs also vary in their viewing angle. This tells you how much the beam of light spreads out. Standard LEDs have a viewing angle of 60° but others have a narrow beam of 30° or less. Rapid Electronics stock a wide selection of LEDs and their catalogue is a good guide to the range available. Reading a table of technical data for LED Suppliers' catalogues usually include tables of technical data for components such as LEDs. These tables contain a good deal of useful information in a compact form but they can be difficult to understand if you are not familiar with the abbreviations used. The table below shows typical technical data for some 5mm diameter round LEDs with diffused packages (plastic bodies). Only three columns are important and these are shown in bold. Please see below for explanations of the quantities.

With everyone going green these days companies all over the world are coming up with innovative new ways to save energy and save you money. Solar geysers are a relatively new concept that is quickly catching on with eco-conscious consumers. Solar geysers utilize solar power to not only heat water but to store its energy. Pipes, connected to hot water storage apparatus utilize energy collected by solar panels. These systems can be used to heat swimming pools, bath water and more. Many in cooler climates with less solar energy available have concerns about switching to solar geysers. These systems can still save energy and money for this group since they can be used in conjunction with gas or electric water heaters. An indirect circulation system is best for these climates. Switching to the solar geysers during the summer and sunnier days of spring and fall can save consumers a lot of energy since solar power costs nothing. It also gives peace of mind that, since solar power doesn’t give off greenhouse emissions that the environment is being protected. Another perk to using solar geysers is that during power outages it kicks in to full gear for consumer convenience. Although the initial start-up cost of installing solar geysers may initiate some sticker shock, the money saved long term cannot be ignored. Since 25-55% of energy consumed in the average home is a direct result of heating water it makes perfect sense to switch to solar geysers. Since these systems also work when the sky is overcast it is a perfect solution for any home.

A Solar inverter or PV inverter is a type of electrical inverter that is made to change the direct current (DC) electricity from a photovoltaic array into alternating current (AC) for use with home appliances and possibly a utility grid. Solar inverters may be classified into three broad types: * Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays and/or other sources, such as wind turbines, hydro turbines, or engine generators. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source, when available. Normally these do not interface in any way with the utility grid, and as such, are not required to have anti-islanding protection. * Grid tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages. * Battery backup inverters. These are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection Solar inverters use special procedures to deal with the PV array, including maximum power point tracking and anti-islanding protection.

Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point, point to multipoint, or mesh wireless links. CCTV is often used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. It is also an important tool of distance education. In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing Digital Video Recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion-detection and email alerts). More recently, decentralized IP-based CCTV cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation CCTV Camera and lens Categories of CCTV Dome cameras, CCTV CS Mount Cameras, CCTV IR cameras, CCTV Wireless camera, CCTV IP Camera, Lens- Fixed and Varifocal     CCTV Recorders DVR Categories of CCTV 4, 8, 16, 32 channel DVR, Standalone DVRs, 4, 8, 16, 32 channel PC based CCTV DVR Cards   CCTV Monitors Range of CCTV monitors both TFT and CRT   CCTV Storage Smart solutions for CCTV CCTV Camera and lens Categories of CCTV Dome cameras, CCTV CS Mount Cameras, CCTV IR cameras, CCTV Wireless camera, CCTV IP Camera, Lens- Fixed and Varifocal     CCTV Recorders DVR Categories of CCTV 4, 8, 16, 32 channel DVR, Standalone DVRs, 4, 8, 16, 32 channel PC based CCTV DVR Cards   CCTV Monitors Range of CCTV monitors both TFT and CRT   CCTV Storage Smart solutions for CCTV storage, CCTV HDD
