LED-TECH.DE 308 XT High-Performance KIT (4000k)

The Samsung LM301 is currently one of the most efficient LEDs on the market and exceeds the 200lm/W limit.

The LED-TECH.DE 308 PCBs offer you completely new possibilities to realize demanding applications. Through the sockets you can easily extend your application almost infinitely.

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.

This KIT includes:

  • 1x LED-TECH.DE 308 XT Board in 4000K
  • 4 Slot Nuts
  • 6 Flat Washer (incl. 2 reserves flat washes)
  • 10cm Input Cable
  • ATTENTION: suspension not included!

The advantages at a glance:

easy installation
- high luminous flux
- individually stackable
- based on constant current
- 308x Samsung LEDs per board

- very good price / performance ratio
- fast and easy handling through plug-in system

- optimized surface illumination, e.g. grow, advertising space

- s
olderless PCB with sockets for rigid strands (0.2 - 0.75 mm²).

In our test, we achieved the following values at an ambient temperature of ~ 20 ° C:

The LED-TECH.DE 308 was supplied with 3.5A without heat sink (~ 140W) and warmed up to approx. 58.8 ° C

- ATTENTION! For use with constant CURRENT only!

*We distinguish the modules between CC and CV modules. Please note the product subtitle.

  • CC module = Constant Current
  • CV module = Constant Voltage

    For the boards we can recommend the following power supplies:

    SYSTEM250 compatibility
    The board offered here is 100% compatible with our SYSTEM250 construction kit. Our support will gladly assist you in the planning/design of your personal SYSTEM250 application. The gallery shows a sample composition.

    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.
