question for Vortigern

Hi and what would you like to hear about?

 

[toplightco]

How many panels have you put on one MCB? and what control gear are you using and what make of panel? This is a well know problem and there are a couple of work-arounds for it. So don't panic-yet anyway.

Would love to hear more about this and what 60cm x 60cm panels you would recommend?

Depending on the location spec; JCC for general lighting of offices and toilets/hallways. Very good colour rendering long guarantee and good tech service. For High end Cree very high CRI for special applications such as art studios. We have use others however JCC are quite markedly brighter and truer colour rendering. They have just brought down the wattage and still produce the same lumens so what was a 44w 3000 ish lumens has now dropped to 36w I think. 7 Years commercial guarantee and automatic now you do not have to register it all on the www.

Thanks, that's interesting. There are Soooo many LED Panel suppliers out there some vv cheap indeed and its hard to know at a distance if they are any good. What would you say are the warning signs to look out for?

I do not look so much for warning signs as compliance with the IET book on code of practice on the application of LED lighting systems. I also check on the ESC site for withdrawn items of all types. There are many LED lamps that have been withdrawn for various safety reasons. The code mentioned requires various BS standards to be confirmed and the parts for the system to be endorsed by the manufacturer in writing. i.e. control gear switches and panels. And I get that in writing! Having said that I have just recently used Denmans £25.00 led panels (Steeple) 2 year guarantee and been surprised at the quality of the light but doubtful about the quality of the construcion materials.
As you may know there are quite a few considerations on compatability in terms of supply and what else is on the system. i.e. mixing LED with old switch start fluourescents can cause problems with transients. So it is more (for me) compatibility and endorsement with guarantees to ensure a solid and durable system is installed for the client, with back up from the manufacturer. I have seen stripdowns of CE (chinese export) showing lack of earths and all sorts of egregious manufacturing techniques which tends to lead me away from just buying any old panel.

Such a useful post, many thanks indeed. Your point about manufacturer back up being important is so true and it's something I shall bring up the next time a customer tells me the product I am recommending is too expensive!

I am happy to give the customer a choice however I will only go so far in terms of quality. And I certainly put it in writing and get the agreement signed by the client. Paper trail at all times!
