HPS vs. LED - IMPROVED pic using camera!
Now heres a much clearer photo of the HPS vs LED comparison in Lakewood CA. Which do you like better? Well well I think I read the minds of most, they would choose HPS lol.

I prefer seeing CMH and induction lights to LED, the LED traffic lights here sometimes have a pretty big colour variation...the greens can range from green to bluish and the LED pedestrian signals range from white to bluish white.

Thats right I am still not a fan of LED traffic signals they are too bright and glary at night but oh well gotta live with it.

I like metal halide over HPS. I believe that with some more design changes, LED could become the universal light source for any application in the distant future.
Silverliner14B   [Sep 18, 2011 at 03:24 AM]
How can LEDs be universal? They can't replace incandescents in ovens, never will be. Additonally, traditional light sources are not going down without a fight. Sylvania now makes fluorescent lamps that last 80,000 hours, thats longer than any LED fixture designed to replace fluorescents.
streetlight98   [Sep 18, 2011 at 03:26 AM]
Never did i say i wanted it to happen. I don't want incandecent, fluorescent, and HID lighting to go.
joe_347V   [Sep 18, 2011 at 03:30 AM]
I don't think traditional light sources will go away that quickly since they still have practical uses and light sources like incandescent will probably still be used for decorative purposes.

And I never really did like the LED traffic signals in terms of appearance they're too glary at night and some look like they flicker, but they do use a lot less energy than the incandescent signals.
streetlight98   [Sep 18, 2011 at 03:46 AM]
I only like the non-pixlated LEDs. I don't mind the brightness, althogh at night it's a bit powerfull. During the day especially at sun set and sunrise, you need it brighter or else you wouldn't see what color it is.

the LED Traffic lamps with individual diodes visable are pretty much out of the picture now...you don't see them new anymore,it's all about the incandescent look ones.

LED's work great for Indicators,Flashlights and Traffic signals...i don't see them for roadway lighting.
joe_347V   [Sep 18, 2011 at 04:06 AM]
I still see them all the time and a GE RX-11 got installed recently too if those those count as pixellated LED signals. Razz

But almost all new LED installs are incandescent look except for bi-colour arrows, ped signals and countdowns.
streetlight98   [Sep 18, 2011 at 04:11 AM]
The bi-color ones here are non-pixlated.
LilCinnamon   [Sep 18, 2011 at 06:57 AM]
I choose LED, I prefer those colors over HPS. xD
Form109   [Sep 18, 2011 at 07:21 AM]
even though its white light im picking HPS because its HID and LED Streetlamps are Gull Choclate. Razz

I don't think LED's are appropriate for streetlighting, I'd rather see pulse start metal halide and induction. I do think LED traffic signals are better since they're more visible than incandescent ones.
streetlight98   [Sep 18, 2011 at 03:19 PM]
I agree. I like LED traffic signals becasue they're more visable and the color is better. I'd like to see pulse metal halide or ceramic metal halide lighting the roads, but don't see that happening here.

I don't like induction or LED because i always enjoy seeing the streetlights start off dim and gradually warm up. It's more interesting.
Silverliner14B   [Sep 18, 2011 at 06:41 PM]
@Michael, induction lamps do start out dim, like at half the brightness when turned on. They reach full brightness within a few minutes.
GullWhiz   [Sep 18, 2011 at 07:03 PM]
Yes, they do start out dim almost like a fluorescent light in the COLD!!!
gailgrove   [Sep 18, 2011 at 07:10 PM]
Hang on a minute everyone, does anyone know anything about this LiFi or light emitting plasma? This seems to be yet another light source trying to eliminate HID, or maybe it could even be considered HID? They seem to have a "cobra head" (and I use that term loosely). I'm not sure what to think of this source yet.
joe_347V   [Sep 18, 2011 at 07:13 PM]
Nope, I've actually never heard of it until now.
streetlight98   [Sep 19, 2011 at 12:41 AM]
LiFi? Never heard of it. Sounds like something in a videogame. Laughing The heatsinks on that LEP light ruin the design. Heatsinks do not look good when they practially cover the whole light. Rolling Eyes
Silverliner14B   [Sep 19, 2011 at 07:27 AM]
Isn't the light emitting plasma lamp some sort of an induction metal halide? I still don't understand fully about the technology.
