LED: How to retrofit 400-watt metal halide lamp

[@dafarmer4922]

I ordered T8's at a trade show. For months, I got constant phone calls from the ELS sales team, trying to sell me more. Getting rid of the ELS sales force was like trying to get rid of herpes. I started off answering the calls and explaining that I had not had time to clear the floor of my building and rent the man lift required to replace my current bulbs. The calls persisted. Think of 'your car's warranty' type calls. I stopped answering. So then the salesman decided that if I don't have time or inclination to answer his calls, he would come by my place. Ugg. I crawled out of a piece of heavy equipment I was repairing and explained to him (again) the situation of not having time to clear the floor and put up the new bulbs. I even pointed out the new, unopened box of ELS bulbs next to the door where they had sat for months. When comparing the box to my existing fixtures, he realized that I had the wrong bulbs! Thank goodness I didn't do all that work only to find it out myself. So he ordered the right ones. And they were actually cheaper than the wrong bulbs- good news! So he ordered a few more to make up the difference in what I originally paid for. Better news! Then the calls started coming from the ELS office in Wichita, Kansas. YOU OWE US MONEY! I called back and left a clear, concise, profanity laced message explaining the situation. The sales manager called me back and told me sorry, they were wrong, he had had nothing but troubles with the new office manager and all would be taken care of. Wonderful. Don't call me again. I'll call you if I ever want more of your bulbs. But I wont. Flash forward a couple months and, surprise- my account is in arrears. I am sent a notice of over due bill for the charges that were wrong in the first place. I left another, less clear, less concise and even more profanity strewn message for them late last night. Fortunately, I still haven't taken the time to put up the ELS bulbs. I want to return them and never have anything to do with this company ever again. My experience with this company has been very negative, to say the least.

Thats awful that this happened to you but I would really like to see a response from the company as to why this happened. When companies ignore customer complaints like this, it seriously throws up red flags.

I installed one of these to replace a compressed mercury dusk to dawn , 250 watt , removed the starter, light works but no dusk to dawn option anymore!

[@jameshill4900]

Should work. I just did 2 of mine on similar lights with the puck style photo electric sensor on top. Check wires. Your sensor maybe gone. The ones I had on wouldn't shut off before the retrofit so I put new sensors. Works perfect.

[@MegaRiffraff]

It was the sensor

[@pedroaguilar3237]

Could you wire this straight to your power supply in the ceiling?

[@StarboundSound]

Yes you can

[@pedroaguilar3237]

OK. I will try. Thank you for your time and knowledge.

I have some HPS explosion proof housing fixtures, they are sealed enclosures and water tight, would your cob LED bulb be too hot inside of my enclosures? Would the extra heat shorten the life of the bulb much?

[@edisonlightingsupply7093]

Our corn lamps are rated for enclosed fixture usage.

[@bivica.fivigum]

You are NOT allowed to retrofit explosion proof fixtures with corn lamps!!! The lamp will void the Class and Division ratings of your fixture.

I thought Jay from Modern Family sold closets?

[@coreyscheidt]

Is it possible to put a plug in on these like a lamp?

[@Mr_Clean]

Yes. I have 8 in my garage. Mine are multi volt and i had to set them up for 120v they were set for 477v. Its just connect the wire with the metal 120 tag on it.

[@mcdugal2]

Would I be able to use this lamp to retro fit a 54 watt mercury-vapor outdoor post lamp by bypassing the existing ballast?

[@ALT-9167]

Duh!

[@scottickes284]

It could still hold a charge always treat it as if it was a live wire

[@ikeith85ik]

Yea, so true. Not paying attention, he could've easily shorted that thing out and discharged it. Surprise!

[@Yakuza5150]

Could you please tell me where i can purchase the corncob bulbs that you describe, thank you

[@edisonlightingsupply7093]

We have them here at our warehouse. Please give us a call at 1-866-643-0555. We will be glad to answer any questions for you. Than you!

Corn cob lights are a waste in this application. Almost all your light shines out to the side, not downward. Just look at the design. I don't want to light the leaves on my trees, how about the ground???
