90W of LEDs sounds like an awful lot (some people would say equivalent to 500W - 1000W of incandescent). Can you believe that it is only 'equivalent' to 144W of fluorescent tubes?

The fitting is desighned to replace an existing 4 x 36 fitting, isnt that what they are refering too, and the light output is at least, if not more
The ones we use are 3600 lumens

Yep, they say "7800 lumens, equivalent to 4 x 36W fluorescents"
Fair enough - doesn't 90W of LEDs sound like an awful lot to you, like it does to me?!

Well it is a big panel, and ive seen 50 watt floods and we fit some track spots that vary from about 20w to some over 30w.
To be honest im a bit lost with the Wattage V light output lately.
Maybe i need 24 hour care

Me, too - but if one thinks in terms of any of the commonly quoted 'multipliers', 90W of LED ought to be equivalent to an awful lot of incandescent lamp/bulb!

Hi Berardgreen, panel looks good, but we have a vaulted ceiling so would need one either side, and they may look a tad cumbersome.
As it's a insulated vaulted ceiling with a glulam beam running down the middle we have 2 options.
Either down lights as should be able to squeeze 50mm depth in, some sort of hanging lights, or a long track/spots on bottom of glulam beam. Down lights/hanging lights are more hassle running wiring through ceiling as compared to track and spots.
Just can't decide
A 36w T8 fluro is rated to 3350lm
How can they claim a 7800lm panel is equivalent to 4x3350lm? can they not do basic math?
In lumens per watt, HF T8 Fluro will usually beat LED's, and it certainly seems to be the case with that panel...
90w for 7800lm is 86lm per watt
144w for 13400lm is 93lm per watt.

How wide is the beam? What colour is the ceiling?
Hi, beam is 100mm wide and the ceiling will be white when finished.
Fair enough, but incandescents are, IIRC, around 10-16 lm/w - which means that you're talking about the equivalent of around 500W - 1,300W of incandescent lighting - which sounds like an awful lot to me!

Yeh i guess it is a lot. My kitchen (~4.5x3.5m) happens to have 4x 36w fluros, and its bright for sure, but not in a bad way. I do have black doors on the kitchen units though which i guess makes it feel somewhat darker.
To me it just feels "well lit". Interestingly it has made me realise so many other peoples kitchens are really poorly lit!
Previously we had 8 GU10's on those directional bar things which made the room gloomy and dull, despite the 400w of lighting.

Fair enough - but per the figures that you and I mentioned, that should be equivalent to about 840W - 1340W of incandescent (i.e. 'around 1kW') - would you ever have contemplated that much to light such a kitchen?
Kind Regards, John
Possibly a good scenario to use concealed LED strips or cold-cathode neon tubes?
What is the detail at the apex - as on the left, or the right?
If as per the left, and the beam is not an architectural feature you want to preserve, then you could have concealed lighting reflecting off the ceiling.
Hi Ban-all-sheds, it's as apex on the left. That's not a bad idea, I'll have a look at how it would look.
