49x Samsung LM301B Square 50 High-Performance 4000K

Solderless square PCB with sockets for rigid strands (0.2 - 0.75 mm²).

Easy feeding without soldering! The insulated conductor is simply inserted into the clamping point as far as it will go and automatically fixed securely. Please use solid and stripped wires.

Successful usage of high power LEDs:

Heat management
Applications with high power LEDs need enduring, adequate and plane heat conduction from the first moment of use. It is very important and neccessary to get the heat off the devices to ensure the maximum light output, lifetime and efficiancy.

Drive management
LEDs should be run with a constant current in addition to the manufacturers recommendations. To ensure this we recommend to take constant current power supplies because resistors are always a risk factor in high power LED applications.

IP protection
Unless otherwise stated, the modules are not protected against high humidity or splashing water. If LEDs are used in areas that require increased protection, this must be manufactured according to the requirements.

EMC protection
LEDs are sensitive against heat and electric charge. Please avoid any kind of short circuits or electric discharge to the illuminant. The chip can be damaged or even destroyed.

Storage / JEDEC level
The storage temperature should be from -30°C up to + 80°C in dry ambience. After opening a sealed bag the content should be mounted rapidly. Once absorbed humidity can be removed by tempering the LEDs in some cases. More information can be found in the manufacturers datasheets or on the manufacturer homepages.

Soldering conditions
Each LED has its own soldering conditions that the user should pay attention to. After the launched lead free processing specifications many standarts have changed. Information about recommended soldering can be found in the manufacturers datasheets or on the manufacturer homepages.

Delivery time

Deliveries within Germany take 2-3 days beginning after receipt of payment, for deliveries to invoice beginning with the shipment, for deliveries to cash on delivery beginning with receipt of order. Payments and incoming orders beyond our business hours let the delivery time begin with the next workday. For deliveries to other EU countries the delivery time may be extended up to 3 weeks. The delivery time is subject to the proper delivery of the logistics company, as far as delivery delays are not caused by us. The validity of the above delivery times requires the availability of the ordered goods from stock at the time the delivery time is beginning.
