LED-TECH.DE 308 COMPACT High-Performance PCB (3500k)
The Samsung LM301B 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.
The advantages at a glance:
- up to 233 lm/W
- 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
- solderless 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 2A without heat sink (38.6V, 77.2W, 15.500lm) and warmed up to approx. 50 ° C
We distinguish the modules between CC and CV modules. Please note the product subtitle.

Successful usage of high power LEDs:
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.
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.
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.
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.
