Bridgelux Vesta® COB Dim-To-Warm 20W CRI90 1800K-2700K (LES 13mm)
Vesta® Series Dim-To-Warm Array products deliver adaptable light in a solid state lighting package. Vesta® Series products tap into the powerful mediums of light and color to influence experience, well-being, and human emotion. They allow designers to mimic daylight to increase productivity and well-being, retailers to influence shopper behavior and fixture manufacturers to simulate the familiar glow and dimming of incandescent lamps. This high flux density light source is designed to support a wide range of high quality directional luminaires and replacement lamps for commercial and residential applications.
Lighting system designs incorporating these LED arrays deliver comparable performance to 150 Watt incandescent-based luminaires, while increasing system level efficacy and prolonging service life. Typical luminaire and lamp types appropriate for this family include replacement lamps, down lights, wall packs and accent, spot and track lights.

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.
