Real power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the current and voltage of the circuit. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power will be greater than the real power.

Test report is expected for end of Nov. -Is there a LM 80 report - LM 80 Test is started. As of the amount of test hours (6000h) final report is expected for Q3 2012 -Is only 3000K available - Other CCT than 3000K is possible. If there is a customer need for a different CCT we have to feedback HQ - What color binning is available - Right now we offer the main Bins G and H. A subbining, as with our other products in 6 Bins per main bin, is planned -Is there information on Tj, Rth, dielectric strength - Data shets will be updated in November and include this information A Company of Good PeopleA Company of Good PeopleA Company of Good PeopleA Company of Good People 17 ■■■■ Introducing new family of Acrich 2 -Acrich 2 Family - Questiones and answers -Is there a luminous flux bining - Not right now. -What are our expectations on intensity for the future - We expect an increase of luminous flux of 5% per quarter. -Is there an application note on thermal management - This will be released in November 2011 -Why is flickering improved compared to former products - Based on the used IC we could reduce the off time of the LED remarkable. Therefore there is no impression of flickering any more -Do we suggest an optic for the 4W unit for MR - We are in conact with a lens manufacturer and expect samples begin of 2012
