💡LED Light - Never Use Corn Light Bulbs 🙄

- In this video, we explain the logic behind why LED Corn lights NEVER work optimally in any setting. The output of a 150w LED Corn light reaching the floor is usually ....🔥 Click on 'Show More' for details (...)
The output of a 150w LED Corn light reaching the floor is usually 20-40% of the lux levels provided by a dedicated 150w LED High Bay with all the LED chips directed towards the floor.
So any saving made on the installation will be countered by reduced productivity and Health & Safety issues.

The flaw in your logic is that the original light bulbs , Albeit MH or HPS ot LPS or even the old standard Mercury Vapor bulbs also had at least 50% of the light going in a direction that it was not needed . All of this said comes back to the quality of the fixture its self . The important thing is the reflectors. This is what directs the "SPILL LIGHT" back to a usable direction . . Better yet is a light fixture that has a true Mirror reflector . All of this said , A LED light where all of the emitters are exactly directed the way you would like them is in truth impractical to have for all applications but Yes it is the most effective way to get every possible lumen out of a light source. With the multitude of applications out there one must make informed choices.
I use them for construction work lights.........they're great, and last forever.
install in a reflective focus fixture.
Yeah but you do lose some like (depending on reflector quality.)
the LEDs pointing in the wrong direction theory does not make sense. A MH lamp does the same thing. There are NO reflectors on the MH lam[p itself to point the light in a downward direction. Most high bay lights have a giant reflector on them to point the light downward.
Nothing like a bias support, lol he sales metal hylide bulbs
Hi Daniel. You are right that I am biased, but only because we are often called out to replace LED Corn Lights due to low lux levels. We always recommend replacing Metal Halides or LED Corn lights with our LED High Bays that increases the lux levels significantly and provides strong energy savings.

I've never seen a guy so passionate about LED lighting. I'm convinced!
Omg... The light on the side is important too...
Are those CFL tubes in the ceiling of that warehouse? Round CFL tubes, not 'directional'?
good for all round light output fixtures
Definitely.
what about peaches and cream corn lights?
Hello, Mr. Lauritzen. I want to comment on your statement that corn cob light bulbs are inefficient to use in your hausehold. At some point you might be right that design of these corn cob light bulbs are not ideal for general use in most houses. According to my observations they would not be used like a traditional ceiling bulb but more for photography and/or videography purposes and most of the time, inside of a softbox. From my own experience with corn cob light bulbs, I would not say that they are useless. I use them in my softbox for photography or video works and I can only say how convenient they are. I also do not agree with your statement that you get only 25% light from the bulb because only a small portion of the bulb will be pointed towards the floor. First, if you ever heard about "photons", they do not travel on a straight line in the spaces, especially in a room. These photons bounce of the ceiling and walls, though they come from a sort of direct light source. If we consider that most of the people's houses are with white ceiling, reflection and therewith the light spill will be increased. Second, you compare the corn cob light bulbs with traditional light bulbs, which should not supposed to be used in a same way. Your argument is more like to say, "don't use truck wheels on your car, just use X company car wheels". Lastly, I would suggest you not to forget to mention the addressees on the title of your video to make sure WHO should "never use corn light bulbs".
Was given one of these (looks just like the one in this video 150w) I was wondering if I can screw them into my outside flood light receptacle, its the standard two fllod light outlet you can buy for $30 bicks at Lowe's. I'm concerned that it might get to hot for the fllod light fixture its screwed into outside?
Are you based in the U.K.?
So what is your alternative solution?
We always recommend replacing Metal Halides with LED High Bays like our PS-UFO-MAX. They have 160 lumen/watt energy efficiency and directs all the light to the floor, which increases the lux levels significantly and provides strong energy savings.
As a rule of thumb you can replace a 400w metal halide with a LED high Bay of 120w/19,600 lumen. This will save you 70-80% on your energy bill and double your lux levels for Health & Safety.

#givethanks. Thank you for the warning. Glen M
I want my walls illumiated.
The corn light should work in high bay enclosure as its in a reflective enclosure and thus directs the light downwards, high bay light fitting has to have some of the guts removed as not needed to run LED lights, right?
The LED corn lights do work in a reflective enclosure, but only a part of the total lumen output will reach the ground directly or indirectly. A better and more durable solution will be to replace the Metal Halide fitting with a brand new LED High Bay, which will ensure that all the LEDs are pointing towards the ground and last 5-10 years.

Just get the corn bulb that is directional
Why the short life expectancy ? LED bulbs last the longest and run the coolest...Are you sure about your stats ?
Hi Coil. The short life expectancy is not due to the LED chips, but due to retrofitting them into an old fitting which was built for MH bulbs. Both the Metal halide casing and the Corn lights have long life certificates, but they are not optimal together.
For a long term solution lasting 5-7 years, we recommend to exchange the Metal Halides with new LED High Bays such as our PS-UFO-MAX ruclips.net/video/Cm7Q96h0xUA/видео.html

Retinal damage with even low exposure. Read up. These things are dangerous.
cobb lights not corn.
Totally agree, corn cob lights are a waste of money and a big gimmick. Anyone who has a clue about led's, can see this is a horrible design, a money maker from the uninformed.
