Everlast’s PVW Hybrid Street Light

I wrote a post about induction lamp technology a few days ago – a company called Everlast is producing a solar and wind powered induction lamp street light.  PV panels, a turbine, and a 70-100W fluorescent induction source.  The system as a whole is pretty sweet – the wind turbine operates at as low as 2-3 mph, and has an electric shutdown after 60 mph.  I would assume that those blades could create some catastrophic failure on high winds, as any wind power collector.

Check out Everlast’s product page on the PVW Solar/Wind Street Light.  It’s pretty interesting!

Induction Lighting – 100,000 Lamp Hours

I have read a lot about the plasma column lamps created by companies like Luxim and Ceravision – electrodeless, high CRI, very efficient, and high lumens per watt.  The sources use radio waves to excite the argon and metal salts in the arc tube to a plasma – in an electrodeless situation.  The idea of the magnetic induction moved into fluorescent technology a while ago, yielding a 100,000 hour flurescent lamp.  There are several companies marketing products in this fluorescent technology – it has a high CRI (94+ in most cases), power efficient, and with good lument maintenance (you know, given the lack of electrodes and all).

The fluorescent induction technology uses the UV light that is returned to the ground state in the plasma material to excite fluorescent phosphors in the lamp.  They still use Mercury (yeah yeah, I know) like the regular fluorescent process, just a different way to excite it.  One of the companies marketing a product is Everlast Induction Lighting – the sales guys there made some videos (thanks for doing this, guys!), and one of them explains a bit about the induction technology.  The video:

Do you remember the article I posted a while ago about the guy (Richard Box) who created an installation of fluorescent lamps just stuck into the ground under a high power transmission line?  The fluorescent tubes all just glowed like they had power – the process of the magnetic induction fluorescent is similar – an electromagnetic field excites the phosphors.

The companies selling the flurescent induction products offer dimmable versions of the sources – have you designed any lighting systems using this technology?  Have you tried any of these products from any company marketing the fluorescent induction lamps?  Please post in the comments!
