1) Luxeon 1W model consumption
- In direct current DC (electronic transformer): 146mA at 11,89V or 1,74W real
- In AC alternating current (induction transformer): 122mA at 11,81V or 1,44W real
2) Luxeon 3W model consumption
- In direct current DC (electronic transformer): 385mA at 11,89V or 4,58W real
- AC alternating current (induction transformer): 253mA at 11,71V or 2,96W real
Question: how to explain the big difference for the 3W model between AC and DC ?? (35% less consumption in AC)
A light output test is in progress: in fact I started but I noticed that a small variation in the angle of the spot greatly influences the measurements. So I have to prepare a kind of rigid support to make the measurements more reliable. But the output seems similar to that of halogen spots: it certainly consumes less but it also lights up less ...
