Track types are not cross-compatible, and that is the first thing to settle. How many heads per metre, where to position the rail, beam angles by distance, and the 30-degree aiming rule for artwork.
Lux levels by zone, pendant heights over fixed tables, why CRI 90 is a commercial decision rather than an aesthetic one, and the glare check to run from every seat before you open.
Will this work in my house? Voltage, plug types, bulb bases, dimmer compatibility and certification marks explained — plus the specification list to send your electrician before first fix.
One measurement decides whether a handle fits: centre-to-centre. How to measure it, the standard sizes, how long a handle should be for a given drawer, and the corner clearance problem nobody checks until the door jams.
New knobs are the cheapest real change you can make to a kitchen, and the job people most often do twice. Diameters, the corner rule for placement, why screws come out wrong, and how finishes age.
A children's room has to work for nappy changes at 3am, homework at 6pm, and falling asleep at 8. That is three different lighting jobs, and one ceiling fixture cannot cover them.
The fixture that fails after one winter was almost certainly under-rated for where it was mounted. Here is what IP numbers actually mean, the mounting heights that work, and how to light a garden without turning it into a car park.
Overhead light on a face casts shadows in all the wrong places. Here is the side-lighting principle, the mounting heights, the CRI number that matters, and how IP ratings work in a bathroom.
Bedside lamp or wall sconce? How high should it sit, and how bright? The measurements, the colour temperature we recommend, and the reason most bedrooms end up over-lit.
One ceiling light doing all the work is the most common lighting mistake in a home. Here is how layering actually works, with the four positions we tell customers to fill and the order to buy them in.
Two pendants or three? How high above the counter? We have answered these questions a few hundred times, so here is the whole thing written down, including the spacing maths and the mistakes that only show up after installation.
A chandelier that is six inches too small reads as an afterthought. Here are the three measurements we walk customers through before they order, plus the clearances that matter over a dining table and in a stairwell.
