    Interesting. I've still been ignoring LED for home lighting purchases, on the assumption that they're wildly expensive, ridiculously weak, or both. But if I compare e.g. http://www.conrad.de/ce/de/product/800892/ and http://www.conrad.de/ce/de/product/757000/ the LED one is actually looking quite reasonable. I'll take LED more seriously next time I need something.

    One question is how humidity, dust, and other airborne contaminates will affect the lifespan of these CREE LED lights being open to the ambient environment.

    It is a nice idea of the cooling.

    However,  since it seems that there is no more space for electrical driver,  and the lamp may use AC-LED with multi-serial-connected junctions inside the LED package as light source.  I strongly doubt the reliability and the efficiency.

    Cheap but sacrifice something else.

#Security weirdness of the day: I followed a link to #Instagram, and it told me they'd noticed an unusual login. Now I hardly ever log in to Instagram, so I imagine any login would be tagged as unusual. But this login - which blocked me from viewing a public post until I answered whether it was me or not - was from two months ago. I have no idea if I logged in then. I might have, for whatever reason, but who remembers where they log in for several months? Not I. The follow-up page had me change my password, without any other kind of challenge. I got a mail afterwards, but seriously, that's some weird shit.

If only the sun flares in my photos were this impressive.

If only the sun flares in my photos were this impressive. Originally shared by Astronomy Picture of the Day (APoD) A Solar Filament Erupts Image Credit: NASA 's GSFC, SDO AIA Team https://apod.nasa.gov/apod/ap180916.html What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere, causing visible aurorae. Loops of plasma surrounding an active region can be seen above the erupting filament in the featured ultraviolet image. Although the Sun is now in a relatively inactive state ...
