Japanese anti-bug lamp.
Added 2019-11-13 01:39:47 +0000 UTCThis lamp is part of a box of stuff sent from Japan by Jerry and Rosie. Jerry is a bit of a lighting geek and works both in the UK and in Japan doing street lighting and signage.
The lamp has fairly standard circuity, but what makes it unique is the phosphor on the LEDs. I've never seen such a ferociously yellow lamp. It puts low pressure sodium (SOX) street lights to shame.

That could make load balancing their grid interesting

2019-11-18 16:53:09 +0000 UTCI think the cockles are sited remotely and warmed via a tightly focused infrared beam.. I too love my UT210E, I notice there's a new model - UT211B - has 5999 count instead of the UT210E's 1999 and a 600mA DC current range..

They are pretty useful because they are thin enough so they fit inside a wallet and you can determine the spectrum of a lamp better with it. Try getting the 1000 or 500 lines per mm ones. I got one in my wallet at all times.

2019-11-13 22:23:14 +0000 UTCJapan is a bit unusual in that they run at both 60 and 50 Hz. 60 in the western part of the country, and 50 in the eastern.
