Are LED floodlights all they’re cracked up to be , are they cost effective in the long long run ??

[Dozer 73]

Not quite convinced about Led flood lights , installed some about 5 year ago , let’s say 5* 120 W , rough cost £700 at that time , replaced them today at a cost of £500 roughly (price of fittings only) the lights tam light CEF specials not my choice , they don’t really seem maintable , yes drivers can be replaced , but should they pack up , the leds them selfs are they replaceable ?
I didn’t get chance to investigate wether it was driver or Led , was just instructed to install new fittings
These lights aren’t on all night they are controlled by pir , in a yard that is not occupied for most of the dark hours
I would expect them to last longer than this
Presume this technology has come on leaps and bounds in the last 5 year
Thoughts please

My tuppence worth...in domestic situations LED is sometimes a good option, because you are usually only fitting 1 or 2, so the upfront cost isn't that high...however, the reliability/longevity is a factor for most householders. If they have existing halogen floods, it's a quick fix to replace the lamps, and very cheap too. Thus, I usually do that for a few quid, rather than recommend new LED fittings at more cost and with questionable reliability. These "security" lights are only illuminated for a few hours per year, in the winter months mainly, if PIR controlled. Ask the question...2 new bulbs @ £2 each that will last probably 3 - 5 years, or new LED fittings and if they go wrong, it's my fault for recommending the change? Nope, use the simple existing fittings which are reliable and cheap to replace. In high use commercial locations the considerations are quite different. It is important to buy the best quality with a proven record...and there lies the problem. Cherry-pickers, operatives, down-time...or just use old-fashioned wind-down luminaires with the usual bulbs...that gets my vote.
New installation? I have no idea! The reliability of LED is still in doubt, whether it be driver problems or others. So, a thumbs up from me for the old technology...which is a pity as I love to embrace the new stuff...but up a ladder in the cold and wet? Bung in another halogen tube and job done!

I have used Venture LED Corns. They are half decent and never let me down but they are big and they kick out a fair bit of heat!

Did you find out what component failed?. This is a terrible failure rate the trouble you sell this to your clients that it will save them money and two years later all fail makes you look bad.

Exactly my point and quite frankly its a horrible job getting to them. I usually get a heads up when the wholesaler suddenly stops using a particular brand because of high failures, its pretty endemic. However its not as simple as that as i have some BG ones still going after 3 years on dusk til dawn, just not the 50W ones. Each one either was just flickering a single row of leds or were totally dead. They are the type that are sealed with a very very short tail, lol.
I am sure i can find the invoice since i know when i fitted them but in a state or pure rage, i threw them in the bin and screamed at the wholesaler... lol
