Yes, this 30W unit is very bright and very even (uniform light output). It will need a power supply of at least 34v to achieve the specified 1050mA. If 2400 lumens output is correct, this LED is achieving about 71 lumens/watt. This isn't wonderful by current standards - 100l/w is available. As a result of the less efficient operation, this LED will need a heatsink and a decent paste to attach it with.
