Powerful High Power LEDs for lighting

The High Power LEDs are very easy to use, since you just need to connect a suitable LED driver that allows the diode to the correct voltage and current. You can also choose to put a lens on, to focus the light in a specific scattering angle.

The High Power LEDs can be used for any project. For example, to the aquarium or terrarium lighting, special LED lamps or lamps, own-designed LED fixtures etc. We use these internally for various LED projects, such as our Sublight underwater lights.

High Power LEDs require a constant current, and not a constant voltage as used in our 12V LEDs. To make the constant current you have to use a constant current source / supply.

You can connect LEDs in series as shown below, which will send the same constant current through them - if you connect them in parallel the curent will be split, and they will light up less.

Lumen is the amount of light a emitter produces, and is thus the most used number when talking about light. When you want to replace a incandescent with a LED bulb it is very practical to calculate the amount of lumen you need. Typically you only have the wattage, and now how many lumens it lights.

The effectivity of a emitter measures how many lumens it creates compared to how much power is uses - lumens per watt.

An example for a 25W incandescent with 15 lumen / watt creates so many lumens:

Lumen = 25W x 15 Lumen / Watt = 375 Lumen

This means if you want to replace this bulb, you would need a LED bulb that creates about 375 lumens.
