Seriously…Is This a Dumb Move

3 BEER CANS SCREWED TO A BOARD AND SET AFLOAT IN THE LAKE ..

So…this floated up on my shore…but this type of stuff happening  over a wide range of venues  anymore…

Simply no common sense thinking!!

OK….weekend skier maybe would see it…..but some of us cut the wake at a high rate of speed…not looking for killer items in water..

What about kids on tubes ..driver doing a good job for fun…kids have no chance to avoid…a potential death blow

 

WATT…A New Direction

Well..who has wandered around..checking out the new LED bulbs..trying to match one indicator …WATTS…,,to new ish codes on boxes.  Well me..so here is the NEW way to look

We need to look a 3 parameters:  

  • LUMENS
  • KELVINS
  • COLOUR RENDERING INDEX  (CRI)

Lumans:

We can start off with brightness measured in Lumens.  Yup..the higher the lumen the brighter the bulb.  So 450 lm would be about the same as 40 WATT bulb up to 2600 lm which may be about 150 Watt bulb

Kelvins

Next..we can  look at colour feel of your room.   Choose this Kelvin number depending on what room..I would guess rec room really bright..living room a bit softer.  So…2700 to 3500 K soft yellow tone…then..3500K then a softer white of 3500K to 5000K.   The brightest being 5000k to 6500K

CRI

Next we look at Colour Rendering Index,,,this is used to bring out the real colours of an object.   Try a number in the mid to high 80s

A site with un-biased information would be..SAVE ENERGY

 

 

 

Bryozoans ….Moss Animal ish

Bryozoans picture , about 25 mm high, on the side on my dock a few years ago. ..and  usually repeating every summer.   The coral of fresh water lakes.

Research is being done on this harmless plankton eating prehistoric deal..  for cancer cures.

The colonies start with a single near microscopic zooid, which asexually reproduces until it’s got an entire army of clones to hang out with.

Bryozoans are usually an indicator of good water quality, and should not be disturbed or removed from the water.
