The new Cree XLamp XM-L in U4 top rank!

The XLamp XM-L LED is the industry’s highest performance, single-die white lighting-class LED. XLamp XM-L is 20% more efficient than XLamp XP-G at the same current, and can deliver 1000 lumens with 100 lumens per Watt efficacy. The XLamp XM-L LED offers Cree’s industry-leading features: wide viewing angle, symmetrical package, unlimited floor life and electrically neutral thermal path.

XLamp XM-L LEDs can enable LED light into new applications that require tens of thousands of lumens, such as high bay and high-output area lighting. XM-L is also the ideal choice for lighting applications where high light output and maximum efficacy are required, such as LED light bulbs, outdoor lighting, portable lighting, indoor lighting and solar-powered lighting.

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.

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.
