I'm not really seeing any major issue
You say that, but what you then go on to say makes we 'wonder'! You went on to write:
If you choose to fit a 60w led batten it will be a helluva lot brighter than a 13 w led bulb .... Whether it will appear to be 6x brighter i dont know ... The 60w batten would be way too bright for me anyhow I’ve a combination of a 9w bulb on a pir for all the quick kitchen visits and a 13w bulb for more light when working in kitchen
I have the same problem, which I might of thought was a fairly 'major issue' for both of us! As I've said, I personally regard the kitchen in question as being 'reasonably well lit' by the present 17 W of LED (a 5' retrofit LED tube), but am being old that I probably need 60 W (2x30), 72 W (2x36), 80 W (2x40) or even 100 W (2x50) to replace it. I don't really understand that and, like you, fear that it may be 'far too bright'.
I like very bright lighting in only a few places .Under the stairs , the attic and the shed . All of which I don’t spend much time in. I recently changed all the bedroom bulbs from 100w equivalent down to 60w equivalent as they were uncomfortably bright for me
Similar here. Are 'they' perhaps very different from'us'? !!
What I have agreed with from the very start is that the present arrangement of a single 5' (1.5m) light fitting in the middle of a 5m-long room is not ideal (shadows etc. ) so would be inclined to replace it with two (probably each about 'quarter or so of the way from the end' along the length of the room. However, rather than 2 x 5' fittings (hence wattages as above), maybe 2 x 2' ones (probably 20-40W total ) or 2 x 4', or even 3 x 2' ??
However, I have discovered a couple of partial 'saving graces'.
Firstly in seems that things described as 'LED panels' are generally pretty wide (commonly 600 mm), which I don't really want (I want 'length', because of the length of the room, rather than breadth), but a good few of the things described as 'LED battens' are, in fact, not the 'industrial-looking things that look as if they should contain tube(s) (but don't) which I don't find very aesthetically-pleasing but, rather look a bit more like 'panels' to me - so I probably have more choice than I thought. Secondly, having investigated the routing of the switch wiring, it doesn't look as if it would be too much of job to install separate switching for two or more lights on the ceiling.
What do you think?
