Morning everyone.

 

I've had loads of requests for a copy of the lighting design, done by a supplier via the electrical wholesaler,  to be honest 'm not very impressed as it appear to have been done using software and a best fit approach,  based on their range of lights. 

 

look forward to your feedback.

On a cursory glance, am I understanding the drawings correctly that they are proposing effectively only straight downlighters, and e.g. in the bathroom one single blaze of a thousand suns LED? What are the orange lines (e.g. in the bathroom a square, but in most rooms slightly more creative).. are they electrical lines that perhaps go to switches?

Seems to be a plan to achieve a certain level of lighting around each room, using a minimum of lighting fixtures. But, lacking info on furnishing plans, useage patterns, and surface finishes. Equally seems to lack any concept of aesthetic. Looks more suited to commercial spaces.

Sorry, that is truly awful. Ansell are a commercial lighting importer who import low quality far eastern product, they have designed your house like a cheap block of student accommodation, I see spec's like this every week for care homes and student accommodation where the contractor has gone for the cheapest solution (but I bet they will multiply the price of these fittings by a factor of 4 for you) - most of those fittings can be bought for under £20 - I know the Eclipse MultiLED can be had for £16. 

 

These are surface mounted LED bulkheads I wouldn't even put in an outhouse frankly - you would cry if you saw your house with these installed. 

 

I throw Ansell product off spec's all the time and that is not even my money.

 

If you want a lighting design, then employ a lighting designer, either an independent lighting design consultancy or the bigger consultancies have the specialist lighting design discipline. Electrical wholesalers are totally clueless, I bet you they would not light their house with commercial product. I am not being funny, but as said in my discussion re. lighting design above on this thread, manufacturers (unless aimed at high end domestic market), wholesalers, contractors, electricians and these lighting suppliers like Pagazzi are just totally lacking and wouldn't know how to light something well if their lives depended on it - I speak from experience of seeing their specs and designs and I am not just making a bold statement. Sure, you will find the odd designer within that camp who will have the skill and experience, but they are few and far between.

 

As an example of the sort of people I would be talking to:

Nailed it - see my post above...

To be fair, lighting calculations will be done using software - however, I don't think calcs are necessary here - it is a domestic setting.

 

If I was to offer a lighting design service for a client, I would produce a full set of CAD drawings, with all the details, such as suspension heights or wall mounting heights, it would come with a full luminaire schedule outlining all the product, precise spec, colour temperatures etc. I would also provide some 3D renders and a concept board with imagery and sketches etc. it would be a proper lighting package. I would not probably run any calcs for a domestic property, only maybe to check we could achieve a decent illuminance in areas like a kitchen and to check the combination of lighting specified would work well to deliver a good ambient light level - it also then lets me show a client what it would loosely look like. I would not throw a set of lighting level calculations at you and expect you think you are sorted. Those are there for building design, to ensure lighting complies with the regs - what do they expect you to be able to tell, as an end user, from those calcs? It probably, with all due respect, means very little to most people. What a joke. 

 

In my kitchen I am having no down-lights, I am going to use recessed linear details hidden into sections of wall and bulkheads to largely have the lighting almost invisible, the kitchen will just glow with light. There will be a single suspended continuous linear LED product, very low profile, circa 30x7mm - but I will need to mock it up to get the size right in proportion to the rest of the space - and about 4m long, I want it powder-coated burgundy or royal blue or something so it standing out as an object, but not as a light, it will be indirect light only (i.e. uplight only) - this will wash the vaulted ceiling section with light which will provide reflected light and the general lighting to the space.

I, for one, would love to see an image of that.....

Will you get sufficient light at your work areas if just reflecting off e.g. white emulsion ceilings? I have not done any calcs, my feeling is you lose >> 50% of the available lumens.

Well I shall certainly post it on the forum when it's all done.

 

Still at plasterboard stage so a bit to go and I intend on having Christmas off.

 

Got it all designed and ready to hit the go button, wiring is in, so I guess the lighting will be staged some before, some after the kitchen fit out (don't think the suspended element is a good idea to have in when the joinery is being done!).

Yes - the way to look at it is to think of the LED source on the small profile and the whole ceiling area as a luminaire in its own right. So work out the delivered lumens from the ceiling, which in this situation is the reflector. Reflectance of a smooth gypsum plaster painted matt white has a Rho (surface reflectance factor) of 80% - also reflectances are dependent on angle, a direct 0° light source will not reflect light directly back well, but as my ceiling is pitched I gain the benefit of a 30° pitch and therefore enter the better reflectance zone. 

 

If there was concern of delivered lumens then I would just increase the lumen package but I am fairly confident that I know what I need to throw at the ceiling to gain the necessary light level. 

 

I have several lighting details throughout the kitchen to provide a higher level of illuminance to task areas, and indeed to be independently switched to provide a low level evening ambient light. 

 

I'll maybe do a whole post all about how it was designed and calculated when I actually get it installed.

That would be really good, especially if you can give some basic theory and calculations.

So chop chop, no need to have Christmas off just because it is in the middle of the week.
