Interesting. I would be interested in buying a 1000w non-resigned lamp and the new redesigned lamp, and test their irradiance in the same reflector with same ballast (as well as the older version with coir/coil) using my quantum sensor to test irradiance ...
They are only selling 1,000w SuperHPS version now, but the 600w SuperHPS will be coming out soon; it's in development now.
Also, Horitlux is coming out with their own brand E-ballast! They are going to show it at the San Fran show in July; it will be for sale before the end of the year. And it will be "ETL Listed", just as good as "UL Listed" (AFAIK); I think this will be the first E-ballast ETL or UL Listed. AFAIK being "Listed" is better than the other designation, if a lamp is "Listed" one can look up the lamp test.
Lumateks are UL listed now
dont know about the eye product but from other manufactures low mercury = lower yields for example when philips released their green lu1000 yields went down 20 to 25% with no other changes other than the lamp

The 1000w Hortilux has worked fine with the Lumateks for the last year. At least about 100 that I know of.
If you notice between the two bulbs, it seems they just redesigned a wire lead that usually spirals down the filament... still on the old 600's... new 1k's took this wire wrap away. That's all that I could notice when looking at em.
And the Quantums are also UL listed.
UL, CSA, ETL... different testing facilities w different stamps. Only time I've seen it potentially matter is that in CO, some cities have reg's that require, quite specifically, UL listings... so by the books, they don't recognize CSA or ETL, which is just stupid. But just a heads up.
I have heard from both sides, Hortilux do fine in E-ballast and they tend to burn out in E-ballasts. I for one used a NextGen E-ballast with a 600w Horitlux SuperHPS and the ballast failed, not the lamp, after just two grows. I am not interested in newer technology HID lamps (re hertz) in terms of reliability when used with a E-ballast, per se.
I am more interested in using a newer technology lamp (ex., Digilux [what I am now using], Horitlux [new lamps], Ushio, etc.) that is optimized by the newer technology E-ballast in terms in reducing flicker. Reducing flicker will increase the total number of photons a plant gets per day, which often will increase daily net rate of photosynthesis. My interest also lies in photon quality and photon quantity, in terms of initial and maintenance values.
I see no problem using coir/coil, I only started this thread because I have not seen anyone post the new lamp info here before. (unless I missed it?)
This is an important spec: First of all "increased reliability" and secondly 60-100 kHz.I just noticed Horitlux is selling a redesigned SuperHPS for E-ballasts; good stuff (finally, might I add)
Increased reliability under varying frequencies (60,000 - 100,000 Hz)

So it will withstand high frequency a lot better but you need a high frequency electronic ballast. Many ballasts (like the quantums we tested) run at just 35 kHz. Lumatek does 70 kHz and the Humboldt MicroMole does 80 kHz+.
Try to get the right operating frequency from your supplier.
The two problems low frequency HPS lamps have is bent wire frames and acoustic resonance in the arc tube.
In reality a lamp has a sweet spot in frequency response, a few kHz up and down can cause acoustic resonance. Therefore it is always best to develop a lamp for a ballast or a ballast for a lamp which hits the sweet spot.
The Gavita Pro ballasts run 400V Philips electronic lamps at over 100 kHz to prevent acoustic resonance. These have been around for about 5-7 years already for horticulture. So it was about time
