Lighting the Way – Rare Earths in Lighting
News from InvestorIntel:

A few weeks ago, I wrote that one of the major changes that has taken place in the rare earths space was in the lighting market. Fluorescent lights work by having electrons strike the atoms of a rarified gas in a glass tube, stimulating those atoms which then emit ultraviolet photons. Those photons then strike phosphor molecules that convert that high-energy ultraviolet light to the visible light that we read by. Oh, in case you didn’t know, if you are willing to sit under a bare fluorescent light, compact or otherwise, then you are highly trusting of the quality control of the manufacturer, because unless their phosphor coating is extremely uniform and complete, some nasty UV light is going to leak out, which is just the stuff to cause skin cancer. Keep those fluorescent lights behind plastic or glass, everyone, it’s safer.

That aside, a fluorescent light is made by taking a glass tube and using a liquid suspension of the phosphor particles to coat the inside of the tube. Once the liquid is evaporated, the glass tube is heated to the point that the glass softens and lets the phosphor particles adhere to the tube. The tube is then finished by filling with gas and sealing. The fluorescent particles then do the job of creating visible light from UV.

The best phosphors of today use rare earths, like yttrium and cerium as carriers, and terbium and europium as…………… continues on InvestorIntel

Improve dairy cow performance with better lighting
News from FarmersWeekly:

Getting building light levels at the right intensity, and for the correct period of time, could help dairy producers push cow performance to the next level. Aly Balsom  reports.

Ensuring cow-building light levels are similar to those in the local supermarket has helped one Leicestershire dairy farmer improve submission rates, boost staff morale, and up milk yields.

Lighting sheds at a similar level to those in the grocery aisle may seem extreme, but research has shown providing cows with 16 hours of lighting at 150-200 lux, followed by eight hours of darkness, can result in a 7-8% increase in milk yields. There’s also likely to be benefits in terms of bulling behaviour and dry matter intakes.

After hearing the potential benefits from Kite consultant Chris Flint, dairy farmer Martin Beaumont was convinced that addressing light levels was a logical next step, after having already made improvements to general cow comfort.
