I tried using the hot air gun but got bored after several minutes of heating and still no reflow.
So I broke out a propane blowtorch, that did the trick.
Warning, if you try to do it this way, be VERY careful, it is very easy to overheat things and damage them. Heat from a good distance away and only till the solder just start to reflow, then pull the heat away quick.
It is an extra large pcb to match the extra large reflector / light.
Unless you seriously screw up you should never need a spare, it is built to last. VERY happy with the mcpcb and shelf.
Now a custom XHP70 12V mcpcb on the other hand, well lets just say that talks are under way and I have no idea where it will end up at this point but things are looking good.
The lux is defined by the sensitivity of the human eye for the different wavelengths, so a light source that appears brighter to the eye should simply measure a higher lux (eye variations averaged).
The reason that the average luxmeter reads cool white light higher than visibly brighter neutral white light is that it is expensive to measure lux correctly, a precisely tuned optical filter is needed before the sensor that is several times more expensive than what an average luxmeter costs. Instead, almost all luxmeters (also the ones over 100 dollar) read the blue region of the spectrum too high, so that cool white led light gets a higher reading than it should.
Please make a pattern in the PN with the adress-informations you want to get. State/province is not nessesary in germany, but if you want it, you/Neal will get it.
The nifty thing about the PM from Mr Scott is that it should look like coming from me.
We await the test pm now (only send to team members on first 555 spots)
I hope he uses something obvious in the subject line. I get hundreds of emails every day and while I scan through the subject lines before deleting them I don’t want it to fail to catch my eye.
