Tear down of a better quality MR16 LED

I wonder how these would survive running in 12VDC automotive systems (up to 14.9VDC with engine running in some) One of these mounted inside the hood might make for a great engine compartment light… or a pair in the trunk. These look like a steal for the price.

How about 20 of these, or more, in a sealed enclosure with active cooling for a light bar?
Running at 14.4V I would estimate around 12,000 lumen. About $150 for the bulbs.

I need to run one more test, current through the emitters at the various voltages.

High powered light bars arent as easy to build as you might think… or I might think. :bigsmile:

DIY Light Bar - 40 x XM-L2 on copper.

After checking into several of the Chinese light bars, Ive decided that Id be far better off building my own for roughly the same cost. Although many of them advertised high lumens, and several of the off road community bought them and posted good reviews, they still appeared to be severely under driven and cheaply built. All the ones I could find were glued shut. A destructive disassembley using a ban saw revealed a single large mcpcb with all the emitters and a cheap small driver surface mount…

Thanks for the teardown and all the detailed tests.
