Nice that you were able to get one. I wouldn't mind having one of these (they look nicer than the GE Evolve shoes they are installing around here . On the larger versions of these, they just have one big LED chip on each lens (seen this with roadkill lights next to intersections and stuff like that.) 20w LED though seems kind of pathetic, I just checked the spec sheet and it is around the same output as a 35w HPS. Are these what they are using to replace 50w HPS? I suppose if it is white light it might work but it would still be pretty dim.

Yeah they're replacing 50W HPS with these. Slightly dimmer but they actually are OK for 50W replacement. The road isn't super badly lit. If it is super badly lit, it was that way with the 50W HPS so not a big deal. Overall they're pretty dim. Would make an excellent dusk-to-dawn security light though, being a nice warm color, full cut-off, no overpoweringly bright, and only 20 watts! Of course the parents wouldn't allow that though lol. This is also dimmable with the 7-pin PC socket but they're not using dimming controls at all. I assume they will be eventually replacing all the DTL photocells with wireless nodes at some point other wise they wouldn't have bought dimmable fixtures with 7-pin PC sockets (or at least that's what I'm thinking).

These are about 2500L, which is about the same as a 750HR 150W 120V incandescent. About the same color too. I'm actually impressed with this. They look so cheap and crude from the ground but in person it's actually a pretty robust light. The casting of the top housing is way thicker than a typical cobrahead. The unit puts out virtually no heat after six hours of constant operation too. Though for only 20W I wouldn't expect it to lol.

Wow ! This will sound strange but it has that same look as Knight Lol. not to sure if led can get 125lm per watt, I am very careful on "Facts" that they say. well it is cute I will give it that. The screws are for the shields I was told

LOL yeah it does look a bit like Knight. Those three screws are for an optional refactor but the holes in the white collar are for shields.

Oh ok I see now, It is a nice light!

Nice find! Seems like they going back to lower output lights like back in the incnadescent days when a 189w streetlighting bulb was used to light residential side streets. Personally I would go for something a bit brighter. This one sounds good for lighting a yard though.

Yeah I agree it's rather dim but probably reminds older people of the incandescent days.

I find in most cases they are too far apart for lower wattage to work right. My bff is from Denmark so I could never have an LED street light LOL

Yeah LEDs don't shine as far as HIDs. These do OK though since there's a glass ball directing the light instead of bunch of naked LEDs.

Right I find LPS does not go as far as HPS but that could be because we use Greece fixtures, almost no reflective back. I think HPS goes very far and worked very well for RI

Mercury vapor provides a nice soft diffused light but the coated lamps also don't travel too far. The clear MVs worked better regarding photometrics but the coated lamps were a whiter light, brighter, and softer on the eyes.

The Philips elite CMH lamps actually are more efficient than all of the LEDs on the market as well as HPS (5300 lumens for 50w, would be a suitable replacement for 100w HPS or mercury vapor due to the high CRI and white light, and 7,700 lumens for 70w. 70w HPS is rated at 6300 lumens, the highest LED is rated at this wattage is 6950 lumens, and 70w quartz metal halide is 5600 lumens. This would be a good replacement for 175w mercury or 150w HPS.) However, for lower wattages like this, LEDs are more efficient. IMO metal halide with drop lense cobraheads makes for the best street lights. Especially with Philips Elite CMH lamps. LEDs are extremely glarey and have poor optical control. Mercury vapor lights (coated) are easy on the eyes while still easy to see by (my 50w mercury vapor shoebox mounted around 12' high lights up the entire driveway very well) but it doesn't throw light very far either. Higher wattage HPS (150 and above) also are pretty nice during the winter and light the road well, but they are kind of glary and unpleasant.

Yes yes, I am huge into SOX / SOX-E I love the efficiency and color

5300L is not a good enough replacement for 100W HPS. 100W HPS replaced 175W MV, which was about 7500L per lamp and that is white light, so I'd say nothing less than 7000L is suitable for 100W HPS replacement. With any metal halide lighting, the only really suitable HPS replacement is the same wattage, so no savings generated. QMH lamps loose upwards of 1/3 of their output by EOL and CMH lamps can loose quite a bit of output too, though nothing compared to QMH. That's also got to be taken into account. CMH is a brilliant technology but it's not the latest and greatest so you can't sell it to anyone. They all want the new tech, as crappy as it may be. Once LEDs are the best they'll get, the next big thing will come along and render all the LEDs currently being installed obsolete.

It's best to just stick with what you have since no matter what it will be outdated tomorrow. It's like iTunes. Every time I open my iTunes on my computer it asks me if I want to download the latest version. I just stick with what I have since I'm used to it and even if I do click yes, the next time I open iTunes I can just about guarantee the same freakin window will pop up asking me if I want to download the NEXT latest version. It's just pointless to keep upgrading. Especially since the newest version probably has fewer loopholes lol.

Yes, The average person is like Patrick star when it comes to lighting, They see a new thing and go for it.

Sounds like a pretty nice light.
And certainly a good score! (I think it would deff look better with a refractor though )

Looks like a robot of some sort.

Thanks! Yeah would look better with a refractor, though TBH the OEM refractor for these is a bit oddball looking lol.

@ Zarlog: Yeah I've found that virtually all LED street lights seem to have this robot/alien/futuristic look to them. I'm sure back in the 50s and 60s the incandescent lovers thought the same thing when cobraheads made their debut lol.
