New LED streetlight cobra head replacements « on: June 14, 2016, 07:29:42 PM » Author: RyanF40T12
This is what they are replacing the HPS cobra heads with right now in my area.  
Manufactured by Philips and custom made to an extent for our utility company- XCEL Energy.  These are the 48LED 108 Watt fixtures replacing 250W HPS.  They use I believe the 80 LED fixtures for the intersections.  I'll get some night shots a little later.  









Removing the old 250W HPS cobra head

I know I know.  But- I have to admit, I do like these.  You've got a good reliable brand- Philips- good reliable materials, supposedly a 5+ year warranty too- And these are not the annoying daylight 5500k+ temps.  I drove around the big community again tonight to see what progress they've made over the past 2 days and it is a nice pleasant sight.  There are some HPS still waiting for conversion right next to these LEDs and I have to admit.. I like the LEDs better.  When you do LEDs the right way and smartly, it really does look nice.

When the optics are a lens panel this eliminates any chance of this light to be good light

If these day-burn during a 104 degree day they're shot. The local electrical distributor here offers LED floodlights that are rated for a maximum ambient of 35C (95 F), and these are expensive, quality floods too. Recently we have been seeing temps in the 90's well into the evening.

Then it should absolutely not be here in Florida, with temps above 104 degrees.

Why didn't PHILIPS ever make HID Luminaires? is my question?  They made the lamps, but why not use GE Ballasts, Cooper, or even create their own ballasts?

In Europe they did make their own luminaires and their own ballasts/ignitors. Business decision ?

Why do you think so? Because the flat panel is easy to make?

Norelco is their original in the US, later Westinghouse...

It is only these days with the LED's, when they started to use their original brand name.

The lens panel provides no control over glare. Whenever the lantern is in field of view, its lens area is a blinding array of lasers in the eye. Thats what you get with this design, no lens panel can be made that does not have this problem

So does the elementary lens on a refractor or mirror element on reflector HID optic.
You only do not see it from further distance, so see it only later, when you pass underneath it's "target" area. The difference make it appear brighter, but it really isn't.
Even cheepeese e-bay lenses are not that bad, compare to common HID's from the 90's and early 2000's here (not speaking about the longevity of the cheepeese lens, they must have cut the costs somewhere and the material composition is the major, yet on a new thing least visible cost contributor)

When Philips acquired Advance Transformer they did roll out a couple HID fixtures under the Philips name. I think they were only limited to low wattage outdoor metal halide floods, the fixtures looked very RAB-like in design, so maybe Philips used RAB housings (rebranded) and just put in Philips (Advance) gear and lamps. I also remember working on some indoor ultra low-profile MH uplighters that used double ended R7s 150w lamps, if memory serves they were branded Philips "Decoflood" and the ballasts in them were odd-looking magnetic (almost like an encapsulated ballast, but much more compact) that only ran on 240v. That the only time ive seen those though.

Nowhere like that

From wide angle - In HID the emitter area seen is edge of reflector (in clear lanterns) or big diffuser area (in refractor optic lanterns), either of them is the size of the entire lantern's optical compartment. In LED its the blinding dots. And not only at +70deg, but all the way to 90deg

When coming closer - In HID seeing the arctube or individual refractor lines, it is still a magnitude less blinding - The arctube is emitting directly only half the light, other half goes through the reflector anyway, so it is less intense and the in the center of a uniform larger illuminated spot. The refractors take it simply by size, and they are lines not dots, and way more dense. In LED its the same blinding dots

Yes, Philips made HID cobraheads, the Lumec Helios series which they took over. It was offered with a CosmoPolis lamp at one time if I recall correctly.
