I just upgraded my workshop to LED and my gosh.... what a difference. It must be at least 50% brighter and a much nicer cooler light temperature. I should have done so long ago. Good riddance to those fluorescent tubes.
One of my tubes went recently, so I have 50% less... well, only sometimes!
Though I mostly only have one of them ever on, location dependent since recent enough.
Comments like the above are intriguing, but leave lots to question.
In my scenario, I reckon these old florescent lamps were fitted for the optimum lighting in my shed,
and would, perhaps most likely be a challenge to replicate the results with a differing system.
That is, if my experiments with DIY lampshades are the same deal.
(a sweet spot regarding the depth of bulb within the shade)
what's certainly more evident than the "just noticeable difference" featured in James Burke's Connections,
so I've got no reason, not to think of a pitched roof being any different to a lampshade,
and the sweet spot up there, having a greater span than something which,
granted...
might have similar output per watt,
with the caveat being that you must make somewhat of an effort to match it?
i.e, lighting strips everywhere, what's likely to get bashed, rather than high up on the roof,
and likely so... an equal amount of a pain in the @r$e to replace!
Still skeptical of those LED lamps, as it's not often you come across something for nothing,
though I must say I've been impressed by the regular incandescent 60w replacements
for my angle poises, not sure what to call them though.
These ones have a plastic neck, and pleased to see them being sold cheaply in the pound shop, though not quite as good as the expensive Phillips ones, (both scored well with a bash test)
Wondering if there's not some similar replacement like these,
though I note their not rated that efficient either, so perhaps could be why not.
They've got a nice warm colour, what matters for matching timbers, as I found even the florescent ones differing, most notable if you've got a machine painted in Claas green.
A kinda upsetting colour when the light's not right, so I am more than skeptical of those studies too.
