![]() ![]() To do so, information is needed from the datasheet of the LED. The above resource can always be used for determining the light output from an LED, but finding it manually is not very hard. Take note that these are measures for 1-Up stars so if you want more light the 3-Up LEDs are a good option as they are triple the light within the same footprint. We have done a lot of the groundwork here, in a post measuring the brightness of each high-power LED at different drive currents. Now comes the tricky part, selecting the LED and driver combination that will output the light needed. High-power LEDs can take currents from 350mA to 3000mA. LEDs vary on their current ratings so be sure to keep track of this when picking an LED and driver. Current is measured in milliamps (mA) or amps (A). The amount of light (Lumens) an LED emits depends on how much current is supplied. For 5mm LEDs, their viewing angle also affects the light output they give off, for more on that see here. ![]() Note that 5mm LEDs are usually listed in millicandelas (mcd). A Lumen is a scientific unit measuring luminous flux or the total amount of visible light from a source. Sometimes it is hard to tell how bright an LED will be because it is measured in Lumens. LEDs are not only known for their colors, they are also a lot brighter than other light sources. As far as colors go, we carry from 400-660nm. You can always find the color or wavelength of our LEDs on the sub-section of the product page and can even search by color from our LEDs dropdown menu on the homepage. We try to carry similar color temperatures and wavelengths for each brand and type of LED. The LuxStrip can house 6 LEDs per foot and is easily connected up to 10 feet long.įigure 4 – LED colors and color temperature All our high-power LED options can be built on a linear design as well. We also offer QuadPod’s which can hold 4 high-power LEDs on a board slightly larger than the 20mm stars (see Fig. ![]() The boards are insulated and contain conductive tracks for easy circuit connections. Our 20mm 1-Up and 3-Up starboard designs are the best sellers. 1) or are mounted to a Metal Core Printed Circuit Board (MCPCB). High Power LEDs come as bare emitters (as seen in Fig. Cree tends to have higher listed Lumen outputs and is a market leader in the High-Power LED sector. Luxeon, on the other hand, has excellent colors and thermal control. ![]() Some prefer one over the other but that comes with experience and knowing what to look for. We carry high-power Surface Mount LEDs from industry leaders Cree and Luxeon. Both are excellent in our opinion, that is why we carry them after all. In some cases, the nature of the item means that it is non-returnable, for example, due to hygiene/health and personal care/wellness/consumable nature of the product.Surface Mount LEDs are diode(s) that can be placed on a substrate (circuit board) with a silicon dome over the diode to protect it (see Fig. Office Products and Wireless Returns Policy New electronic items fulfilled by Amazon AU can be returned for change of mind, for a replacement or a full refund of the purchase cost of the item within 30 days of receipt of delivery.For information about returning faulty electronics please see Returning Faulty Items.
