Question 1

the picture is too large and covers the description. What's the input voltage?

Accepted Answer

Hello,Drive Voltage(V)   is 30-34V,  input voltage is 110-240V.

Question 2

Is it dimmable? If so, which driver do you recommend?

Accepted Answer

Yes it is Dimmable. I just got one in today and inmediatelly put powered it with my programable power supply as follows.   Plus and minus rails with 0 Volts to start with. Once there I began to increase the Voltage 1 volt higher on each step while looking at power comsumption.   At 26 Volts nothing, at 27 volts light came on, dim and low power compsumption, at 27 it was brigh already, at 28 volts was way too bright for me and the power compsuption was 28 watts.  It didnt even get warm so I did not even come close to half its power rating.  I did this just by increasing the voltage.   So for those who said this is NOT dimmable other than with Pulse width modulation, you could not be more wrong.  In fact each bare LED I have tested, has been dimmable.  Sometimes within one two two volts but dimmable never the less.   Please pay attention to the word "BARE".   Some of my lightbulbs are not dimmable because the electronics used to drive the LEDs do not allow it.  The Bare LEDs I have come accross, all have been dimmable without PWM..   You just need to use precise voltage adjustments.   I am talking millivolts of difference you can dimm the LEDs very nicely from 0 to full light and usually around 80% bellow its their rating, LEDs produce about 95% of their maximum output.   Want to save energy?  drive them to 90% of their voltage Rating and add a on and off frequency of 60 Hertz.  The LEDs will be blinking but our eye persistance will not see it.  We only see an LED that is Full ON.   Just like the old CRT TV's.  They were blinking at evry slower rate and we never saw it.

Question 3

Making a high power flashlight

Accepted Answer

I built a flounder light. Attached this light to angle aluminum, created dam surrounding light and incased it in bar top epoxy so it is Submersible in water. I even put several heat sinks behind it. This light takes ALOT of heat exchange to keep functioning. Even with the heat sinks out of water as light I think it would burn itself out, I only run it For less than a couple of minutes if that out of total submersion.

Question 4

WRT (with respect to) the driver circuit; Is it more critical to monitor forward current, or voltage?

Accepted Answer

Its forward current is 3500mA. And it is more critical to monitor forward voltage.
