PetCo VS Giant

PetCo VS Giant

Click to view full size image

Giant has had the parking lots replaced with LEDs in September 2016. Used to have Gardco HPV19 320w PSMHs fixtures. Now they have Rab ALED 150w.

Giant pic is MH, Petco pic is LED.

So far none of them has failed or went dim.

Anyway to make it so they don't keep flipping back and forth so fast? I have a headache trying to look at each picture individually.

Edited the gif so it last longer between pics.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

I have nothing against LED, but i still prefer Sodium or even possibly mercury, i like my lamps mildly colourful lol

Plus sodium has that "homely feel" atleast in my opinion... LED and MH are kindof dull to me
Honestly i hope sodium remains a good competitor to LED, so i will still be seeing them around when i pass, no hope for mercs or MH but sodium still has an edge against LED, especially the LPS variant (which is oddly rare) and currently still more efficent than LED... kindof confuzzled about why its so rare...

LPS is rare because it's so expensive and nobody (aside from lighting enthusiasts) likes the "nasty" monochromatic honey yellow light it gives off. I like LPS for its uniqueness but I sure wouldn't want entire cities lit by it. No colors!

Thanks FGS. Wasn't sure if you had control over that or not.

I'd still park at Giant co, they have larger parking spots, and the illumination in both shots isn't bad for a parking lot, and I do have headlights on the car just in-case it's to dark, and an LED flashlight in my pocket, and I'm not worried about someone stealing it, I just park my car next to BMW or something worth more, which is not hard since I like older cars you can actually fix..

The average life of quality LED fixtures that I've seen here, is 4 years.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

That's the length of the replacement cycle used for street lights with SOX lamps in them.
It might be longer for SON, as they last 24,000hrs compared to 16,000hrs for SOX

HPS is tricky. Most lamps generally last about six or seven years (which is about their rated life at an over-estimate 10 hours usage per night) but I've found that newer HPS lamps often only last a fraction of that. The electric company uses Sylvania lamps here and those are hit or miss big time. Some start cycling within a month while others last a good five years or so. Yet we have some early 2000s GE HPS lamps that have now clocked like 15 years and still going! Seems like HPS lamps were at their peak in the 90s to early 2000s. By the late 2000s I noticed a considerable drop in HPS lamp quality (right around the time LEDs starting catching on for street lighting!)

Once they perfect something, something else comes along and they say the heck with what they just perfected and then start to dismantle that perfection to make the new stuff look better. They did it with MV in the 70s when HPS was starting to take off. By the 80s and 90s most brands' MV lamps were so terrible that HPS seemed like a no-brainer. Who wants to change MV lamps every two years because they dim out so much? Nowadays new MV lamps don't even get a chance to dim out. They CYCLE or just go out completely after six months! Ridiculous! I know none of us wanted a MV lamp ban, but honestly these current MV lamps are an insult to the existence of all those nice vintage MV lamps. Eye and Sylvania are the only ones making a half-way decent MV lamp out there.

The pictures are good for comparing brightness but thats about it. The rest is lost. It can be seen that the higher brightness does not bring up any more visual information, but we dont know how much is lost to the camera in either picture

Over here (European lamps) :

The HPS were excellent up to mid 00's and are fair even today

The Mercury were excellent up to about 2000. As i see it, by 2000 Mercury was still considered a light source of choice for e.g. footpath lanterns, even though it is not very efficient, it was recognized as providing suitable atmosphere for the footpaths and parks, and requiring low maintenance. Later lamps came without the Whitening composition so they were blackening as they age, though they still sorta manage their rated 4 years

The settings for the pics are the same. ISO 800 at 1/60sec shutter speed. Aperture is fixed. Not sure what is "lost" in the two pics.

The metal halide pic looks like it would be easier on the eyes and not as harsh. Just sayin.

Any machine is a smoke machine if you operate it wrong enough.

The setting preserve exactly the light level, nothing more. Not being in the location means you cant look around and complete any visual information :

- You cant look into lighter/darker areas and clearly see into them, the brightness and depth of the picture is fixed

- You can't render colors yourself to make the scene down to feeblest detail out of it. The camera does the first conversion (from continuous spectrum to discrete R, G, B) and that dictates what colors look like

- You can't render colors well from a limited CRI light source. Our vision can pick the feeblest color information and reference it to actual colors. The camera is not capable of doing any of that

- None of the spectrum related effects take place, as the scene is converted to data according to the camera response and back to contunuous spectrum by the monitor, now using the spectrum of the monitor's backlight source



Quite pointless to use a camera to compare light sources for anything except brightness, as everything else is in the areas the camera can't make out anyway
