Sweet pics!
Is the pad on the bottom solderable?

Don't have mine yet but I will be sending WAY more through it than that. FYI that spec is per die so 4x 700mA=2800mA total.btw, is the max current on the mc-e really only 700ma? or did someone try more......like 1A ? :thinking:
The 700mA figure is accurate if the dice are in series. Of course, that's not gonna prevent me from running around 1200mA through each die. :devil:Don't have mine yet but I will be sending WAY more through it than that. FYI that spec is per die so 4x 700mA=2800mA total.
The spec from Cree is a max of 700mA per die. Doesn't matter how you accomplish that series or parallel. I'll be testing them at 2A per die.:nana:The 700mA figure is accurate if the dice are in series. Of course, that's not gonna prevent me from running around 1200mA through each die. :devil:
This is the picture I've wanted to see most. Awesome work. Notice that Cree actually packs their dies closer together than SSC? And is it just me or does the MC-E's dome have more clarity to it?OH, I almost forgot this pic, nice comparison picture:
Helps to visualize just where you can fit this small emitter.

I hope that failure was without a heatsink, because I'm planning on DDing an MC-E at about 3.7V per die with fresh cells.Well,
I learned something today, you can not DD a Parallel wired Cree MC-E with one C Sized Li-Ion (charged to 3.8V resting) for more than 4 sec. It draws 3.42A and quickly burns up.
Definitely going to need some good heatsinking and a Constant Current driver < 2800mAh...
Any suggestions on such a driver? I may use 3 Ni-MH (3.6v) or one Li-Ion (3.7v), just need to keep the current down...
I'm glad I have a few more, but I don't want to make that mistake again....
I didn't get any chance to test out reflectors :sigh:
Maybe I should series wire, that way I will have a better selection of drivers, Shark, MaxFlex, but all of those wires will be hard to conceal.
How do you know this?By the way - the MC-E does not have a silicone dome! Ist has a glas dome just like the XR-E emitter.
