400W MH to LED Conversion options.

Recommended Posts

Hello all, this has probably been discussed but I have not been keeping up.

I have a customer that has (12) 400W MH parking lot fixtures and (16) wall packs. I got the job relamping this location 10 months ago. The owner informed me that he has been having to relamp this site every 6 months. I should have heeded is words. 10 months later after I relamped this location, 90% of the pole lights are out. I personally installed the new lamps in the pole lights, most of them came on, I think I put a couple of caps in but no ballast were required. The lamps are horizontal mounted. Not sure why the premature failures. I think (5) of the 16 wall packs are out.

Anyway, the customer is considering a change to LED. Does anyone have any experience with the "retro" conversions or would I be better off going for a complete fixture change out.

There are a lot of retro's with a socket type mount, some have seperate drivers, some built in drivers, and some powered by the original ballast.

Looking for some real truths.

Thanks all.

P.S. While I have you reading, I am located just outside of Nashville, TN, licensed, bonded and insured. I am a second generation sub-contract installer. I currently own a 01 L60 Elliott along with a couple of other small aerial trucks. Anyone looking for a installation or maintenance contractor in middle TN, look me up.

We came into a similar job and the customer asked about LED. We pointed them to a few known locations that had some LED retrofits to take a look at night so they could judge for themselves on the lighting. We ended up going with just replacing all the components to the same . We found a lot of bad wiring as well as other issues when we performed the work.

To date a year later, all is well and they haven't had any sudden outages since.

May be Pulse start lamps instead of Probe start lamps. Switching the two, will cause shorter lamp life. See link for description of both. (you may know the difference already)
