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!
I think Induction Lamp will be replaced by LED in 2-3 years. In fact the Induction lamp is not as magic as it it said on net. The lamp efficiency is only 75LM/W,the ballast loss 10%,the reflector loss 15%,the lens loss 10%,how much left? 75*0.9*0.85*0.9=52LM/W. But they told you the pupil lumen….
Dear Mr. Dim:
I have read a lot of the pupil lumen, but I have not found any professional or scientific paper againts or supporting the concept.
I would appreciate any help finding this information.
Best Regards
Induction lamps like LED / SMD have evolved tremendously over past few yrs…particularly in efficiency, reliability and cost.
I believe LEDs will become king of lighting in the residential market but have a way to go in high bay industrial use…..
We have found LEDs fall short of adequate Lux on the workplane when installed at heights above 5m. Additional disadvantage is high cost….
Our industrial clients have found Induction lamps used in high-bay application to be ultra-reliable, deliver superior light output, more economically than most other light sources available today.
EG: In just one case – An industrial client using 260 units of 400w MH lamps 24/7 commenced a trial with 6 units 200w Induction lamps in August 2009 ( Height 5m) type of industry is precision engineering.
After 12 months of continuous use without fault, the client’s staff applaud the lights and a decision made to replace all 260 MH units with Induction lamps…
ROI is likely to be 2yrs and forecast total value of energy and maintenance savings over 11 yrs exceeds Aud $ 1,000,000 …..
Proof in the pudding… but comments welcome…
Hi
I looked at the Everlast website; some important information is missing
viz; How much do they cost ? seems they are frightened to announce this
Why do they fail after just 20,000 hours ?
I saw an induction lamp demonstration circa 1975 on TV, it was the same size as a light bulb, illuminated the whole auditorium, operated at radio frequencies, had a life expectancy of 60 years, and was inexpensive to produce.
So it seems that induction lighting is like the ladderproof stocking we’ll never get to see its real capability while there is money to be made.
