We can all wait and see how it last before the HPS cycles.

colorwise they're fantastic...it's longterm longevity and durability i'd be concerned about.

Induction looks nicer than HPS. As for it's reliability, that remains to be seen.

So far none of the inductions have gone out, but I saw one dead LED in Pasadena.

The inductions are great....from what I have seen in NJ and in MD from the tunnels...the failure rate seems to be very low...mostly the Icetrons since it's the ones i see more and longer rows....in my whole trip in NJ..I only saw TWO out....all the rest worked! in the tunnel...just 2 of them out of 300 was out....

That's great that the fixtures are refurbished old lights. The color of the induction is nice, but they're definetly dimmer than the HPS.

Personally i am not a fan of induction. They are failing there was one store i worked in where almost half of them had died. As far as i am concerned they ate still new compaired to some old Mercury lanterns and SOX we have over here that have done 50+ years hard work!

Yeah the reliability of the old magnetic gear and merc lamps seem to be pretty tough to beat.

anybody else see induction streetlighting beside jace and dave?

I have also noticed that some different brands or types of induction work better than others......some will just fail quickly....while others do better....so it is too early to say they are failures....some stuff may be failures while others do great!

It may be the cheap ones that's terrible!

Last night I saw more of these induction lights on Walnut St and Del Mar St in Pasadena, still haven't seen any failures. They are dimmer than HPS but provided better visibility due to the whiter light.

I'll say that induction does look better, but the reliability is of question. Still, I'll go with any HID over induction fluorescent.

I personally prefer PSMH for streetlighting. CMH would likely be the best, but PSMH is more economical and most CMH fixtures use electronic ballasts.

Every HID source has its ideal applications!

- HPS has a very good contrast rendering. For hazardous areas that's the best type to use.
- Mercury vapour is quite reliable, making it a source of choice where presence of light is essential and its quality or quantity is less important.
- Metal halide produces a high quality white light. That makes MHs the best for parking lots and other commercial spaces.
- LED lamps can be produced in a large variety of shapes, which can come in handy in particular building designs.
- Induction starts instantly and also has a very long life. A perfect application for them is high ceilings and other hard-to-reach indoor locations. Streetlighting would also be a good use for them.

What I hate is not a given light source so much, but rather how it is used. Some sources are simply better suited for a given application...

I still prefer either LPS or MV for streetlighting. (HPS is actually odd compared to LPS, due to the yellow/red continuum, as opposed to LPS that just has 1 yellow line). LPS should also be FCO type and bright enough. MV would be good in rural areas, where the green would blend into the natural environment. (not for the LPS vs. MV discussion).

LPS and clear mercs are also handy near skyviewing stations and such since they're the easiest to filter out. By best, i was referring to metal halide choices. I agree that every light source has it's applications and I also think HID is the only way for street lighting.These "green" lamps have FEWER lumens/watt compared to HPS yet they're advertised at lower wattages to appear to be more efficient. That's what really gets me.

I have to say, I really like these inductions. Very soft and low glare, and some of the closest to MVs as far as aethestics go. Very close to a classic hi-output white mercury lamp. In inductions, there is nothing in the lamps to wear out, and if there is a problem all you do is replace the electronic driver unit. With LEDs there are more things that go wrong, like cold solders and stuff. In this case you will have to replace the LED array(s). A bit more maintenance intensive than induction.

Personally I actually like seeing induction replace HPS...I prefer the softer, whiter light over ugly orange...and I've seen inductions lit at night in residential neighborhood and IMO it's much more "Nighttime-ish" and moonlight-like than HPS...same goes for MV though I haven't really seen any MV cobraheads in person except from very far away in private parking lots, etc. But IMO it brings back the MV look with (Supposedly) better efficiency.
