32-Watt (50-Watt Equivalent) High Pressure Sodium LED Replacement | Light Efficient Design LED-8062M

- After much searching, I finally found a relatively economical LED retrofit bulb that is intended to replicate the appearance of a traditional high pressure sodium (HPS) light bulb.
This is the Light Efficient Design LED-8062M 32-watts mogul base bulb. It is rated to have a color of 2200K, which is very close to HPS. It outputs 4,600 lumens, which is only equivalent to a little more than a 50-watts HPS bulb. This is quite a bit less than the lofty claims on the package, touting it's brightness to be as impressive as a 175-watts "HID" bulb. Exactly what HID source is being referred to is unknown, but it's certainly not HPS, which would have been the most logical comparison considering the bulb's appearance.
The bulb's quality of light seems pretty satisfactory, especially for outdoor lighting. There was some banding appearing on the camera's preview screen which indicates the light has some degree of flicker to it, but it wasn't particularly obvious to my sensitive eyes in the few minutes of testing. The color rendering of the items in the room did show some resemblance to high pressure sodium lighting.
The brightness was unimpressive. It's definitely a good amount of light for 32 watts, but it seems to me more like the equivalency of a 175-watts incandescent bulb, certainly not a high efficiency HID source. In fact, the claimed 4,600 lumens is not too far from what a 200-watts incandescent bulb would output. It draws as much power as it is rated for and has a good power factor.
The next test will be to set up 2 street lights, one with this bulb and the other with a proper high pressure sodium bulb, and compare the appearance of the two side-by-side. I don't think it will be a perfect match, but I think it will be pretty close, perhaps even hard to tell without a control present.

I have a 100 watt HPS bulb in a fixture over my garage door. It is rated at 9500 lumens. I wouldn't buy that LED bulb to replace my lamp, as it is not a good value for the money putting out only 4500 lumens. I want to maintain the light output that I have.
The advertising on the box is very misleading.
I like that the old lights gave off heat during winter.
Me too.
great Video, Very Informative
Thanks
youre welcome@@JordanU
It is interesting that it calls itself a HPS replacement, yet it has an EX39 base. EX39 sockets were used with open metal halide fixtures (like your Southwire hanging work light) so that they could only accept protected lamps. That was never the case with HPS fixtures.
I guess they just reuse the same outer bulb and base with different wattages.
It doesn't specifically say it's intended to replace HPS anywhere on the box or product page, it just shows a lighting temperature graph which puts this around HPS. I really have no idea what this is intended to replace as the efficiency claims on the box certainly do not reflect HPS, metal halide, or anything of that nature.
The outer bulb probably is used with many fixtures; anything to save a dime.
Ballasts can last forever in storage or use. I have fluorescent ballasts that have been in daily use since they were new in the 50s and never had an issue. I have also bought several NOS units from the 60s/70s. The capacitors failing isn't really an issue. I guess on modern junk though, the non PCB caps don't last as long as the PCB caps, but people are afraid of a little chemicals now and they have to use vegetable oil or penut oil in the damn capacitors and then they just explode after a few years because everyone is too damn stupid to make anything that works right anymore.
New capacitors are garbage. The old PCB units were superior.
@@JordanU absolutely, but people are afraid of them, even though they are sealed and very rarely leak.
@@WalterKnoxJust like the air conditioners...
Nice
It's decent.
You know that 175w HPS doesn't exist. 175w is only for Mercury Vapor and Metal Halide lamps.
Both metal halide and mercury vapor at 175 watts output far more than 4,600 lumens, so I still don't know what source of light the box is referring to.
@@JordanU hmm
@@JordanUThey are referring to high-pressure imagination lamps (HPI). They don’t exist in physical form, only in the brains of marketers trying to sell LED replacements for discharge lamps.
Perhaps using incandescent lights to supplement heating in my house could lower my energy bill compared to relying solely on LEDs, which produce minimal heat and might prompt me to use electric heating more. So, it's possible my energy bill could be slightly higher with LEDs than with incandescent lights.
Try Ge Current LED35ED17/730 led bulb
That's not a HPS replacement...
@@JordanU Another brand I suggest is ants-led, they make hid replacement corn bulbs that can be in 2200k.
why 5000k for street lights at night? because it matches your night vison FAR FAR better than yellow, and the efficiency is much better which peaks around 500 nm (red cells), warm sodium lamps produce much closer to 600 nm and has the effective lighting power 1/10th that to our eyes than peak blue-green. Look up Scotopic light for a more detailed description of this effect. You may not like it, but you can see a lot further with it. Same reason night-lighting intended not to greatly distrub this capability at night is red. The only major issue with this is that it does disrupt natural sleep rhythms.
When the roads are wet, I find the cooler temperature light reflects off the road and causes a glare that makes it very hard to see. Perhaps if the LED fixtures had better optics like the old ones did, they'd be easier to see by.
When I saw the thumb nail. I thought it was a hps bulb
It does look close to HPS in person, but depending on the auto-white-balance of the camera, it can look more so in the picture.
4500 lumens is not even enough to replace a 175W mercury vapor lamp. Those are around 8000 lumens. So who knows what kind of make-believe light bulb they are comparing this to. Unfortunately, this sort of thing is common practice in the LED world, particularly when it comes to LED bulbs that replace gas-discharge lamps.
A 50 watt HPS is 4000 lumens
50 is a far cry from 175!
I will never have LED garbage in or around my house. I don't care if they get them perfect to the point where you can't tell a difference, I will not use them. This is garbage just like the rest of them and deserves no home other than the garbage. I am 100% serious when I say I will use a transformer and low voltage car lighting to light my entire house before I use any sort of LED trash.
I agree that LED lighting is not for in the house, but I think it could be satisfactory for certain outdoor applications where the majority of the light is wasted.
They would be better if they didn’t have the cheapest possible components, the LED semiconductor dies themselves massively overdriven in the name of “energy efficiency”, and paper thin tinfoil heatsinks covered in plastic.
The only LEDs I use are older ones with big heatsinks, good quality drivers. Such lamps have lasted a very long time in my house, the newer ones, not so much.
@@HIDLad001I really don't care if the didn't flicker, dimmed well, put out good quality light and lasted as long as they claim to, I am still not using them. They can be as great as they want to be, they will always be trash.
How would they be deemed trash if the build quality was proper and the light output was comparable to incandescent?
@@JordanU because it is still an LED, and LEDs have no place in my home other than indicators on stuff like keyboards.
