Barn lighting

Anyone ever use corn light bulbs in there barn. Any pros or cons.

We have a couple of 36W corn bulbs in a 48x60 barn and they give off tons of light. Cold doesn?t affect them as they?re led.

we use some in our barn,and boy does it make a difference when I'm working on one of the tractors,it's like having led light bars hanging from the ceiling but you can use the existing fixtures.

When 50 years old, a fifty watt filiment bulb will do. when 70 a 45 watt Corn bulb will be bright as day. Jim

Pardon me plz,but whassa "corn light bulb"?????

Ok what are corn bulbs?

I guess they are called that because they look like a corn cob,here is a link

They thread in a standard incandescent socket, very good light. A 36W LED ,corn style (looks like corn kernels) or any style LED is comparable to the same amount of light as a 350W incandescent. In a nutshell a 36W bulb will give off 3.5X the light as a standard 100W incandescent bulb but consume just over 1/3 the power. The one in the picture is 46W.

NOT any downside to those LED's, in general.

On the other hand, define "barn".

If an animal facility with flammable bedding on the floor whatever light source is used should be enclosed and UL listed for such use.

Simple incandescent light bulbs, coiled florescents, LED's, etc. can all fail in a manner that will drop HOT materials on your bedding and potentially cause a fire.

If a REAL "barn" vs a machinery storage building with a bare floor, check with your local code enforcement body as to what is approved.

Things may have improved, but my first endeavor into LED was corn lights. Had to buy them on Ebay because there were none to be found in stores.

Had 100% failure with them! Very poor quality from China, short life.

If you want to use existing lamp holders, might try some Y splitters and use regular LED lamps.

I rewired a mercury vapor yardlight fixture, eliminate the ballast running thru light sensor and put a corn 50w bulb in it , lasted bout a year, im on the third one now, lasted bout year and a half. its on a short pole, easily reach with ladder. they claim they last 50,000 hrs, kinda disappointed, they cost about $12, cheap china junk, one of the reasons I try to avoid buying direct from china now

ome November, I have a mercury vapor running 24/7 (daylight sensor fail) for 10 years.

I did the same. Used a 300w cob LED.
Up side, you can repair it. Can't repair a dusk to dawn LED, have to replace.

My understanding one problem with the corn cob bulbs is the heat they produce. LED's produce heat out the back of each little bulb and the heat cannot escape. The heat trapped inside the bulb destroys it. Especially in an enclosed fixture. New, properly designed LED fixtures have become pretty economical. They put light out on the front and radiate heat out the back.

The second problem with the corn cob bulbs is that the reflector in the fixture is designed for a bulb that produces light in the center, and now you are putting a bulb in there that produces light on the exterior. It does not reglect like it should.

Thirdly, no matter how good your reflector, it will still absorb some light and turn it into heat.

I think you will be happier with a properly designed new fixture.

My 2 cents.

COB stands for "chips on board." The fact that they look like corn cobs is just coincidence, and only to a farmer. Most city people would not know what a corn cob is.

People just assumed the corn cob thing. Never heard them called "corn bulbs" until now, always "cob."

I think this whole "corn bulb" thing is an unfortunate side effect of google translate.

I put them in all my barns at work. The cheapest were cheap and stopped working. I bought $30 and $40 ones from Menards and they are bright and work great. Plus I?ve seen some great electric savings compared to a barn full of 300 watt incandescents left on by my guys!

MY friend's son was putting Leds in my barn as a side job and hasn't been back in a couple of weeks because of on the job injury(cut thumb). It had temp plastic lights hanging down from !8 ft trusses that were there when we bought this place in 15.

Haven't tried the cob lights but have been using LED's in our poultry barns for a few years.
Tried some of the first LED's but they didn't last long, today the know brands are much better, Our mercy vapor yard lights started failing and were replaced with CFL's but they gave off poor light in cool weather and never lasted more than a year, installed the first Howards brand LED yard light 5 years ago and it's still working, put a second one up 3 years ago, last mercy vapor failed last fall after 12 years, waiting for better weather to put up another LED.
Replaced all 32 light bulbs on one barn 3 years ago with Satco brand 9.5 watt 5k LED's, they burn 18 hours per day and none have failed but they are noticeably dimmer than when new and will need replaced sometime this year.
Just purchased some new Overdrive Brand 11 watt 5k dimmable LED's to go in other barn, they are supposed to last longer and be better suited for harsh environments.
May pick up a cob light for my shed to see how it does.

Exactly . Trapping the heat of any lamp inside an enclosed fixture will shorten the service life .

Here's some of my LED misadventures/experience. I have no connection to the seller/manufacturers. Bought my favorites from Amazon. Have also used store bought feit, phillips, sylvania, ge, & true-value store brand.

20watt 2400 lumen 3000 kelvin enclosed rated multivolt LED bulb. https://www.amazon.com/dp/B071F8BHNV/ref=cm_sw_r_cp_awdb_t1_IgnrEbYHQ3BQM
December 2018 I installed 2 of these at work in outdoor sealed metal halide shoebox fixtures when the ballasts died, they have been on 24/7 since then with no noticeable change in output. Specifically chose these because they will take 120-277 v and can survive in an air-tight enclosed fixture.

40 watt 4000 lumen 2700 kelvin LED bulb. https://www.amazon.com/dp/B06W2MSB6H/ref=cm_sw_r_cp_awdb_t1_VinrEbHFFRVWR
I installed 12 of the 40 watt and 2 of the 60 watt versions of these bulbs into freebie take-out 400w metal halide high bay fixtures from work. Removed the ballasts and hardwired the sockets, daisychained 14 fixtures with cheap extention cord, hung in a metal uninsulated/unheated pole barn. They work very well with and without the fancy lexan reflectors on the fixtures. Liked them enough to put several up around the house as well, no failures to date. Replaced 12 100 watt bulbs in one of the boss's barns with the 40 watt versions, he is happy with them.

I used the mogul base adapters on the MH fixtures, no complaints. https://www.amazon.com/gp/aw/d/B07GZD3BR5?psc=1&ref=ppx_pop_mob_b_asin_title#

So far I have had much better luck with the above bulbs compared to what I found at Menards, Fleet-farm, HD and True-value. On price, light output, longevity and color temp consistency. YMMV
