The Module 16 is a recessed 16W LED downlight in white 1,200lm at 3000K, CRI above 92, a40 beam, IP44, dimmable, with afive-year warranty.

CRI above 92 is the reason to buy this, and it is genuinely high.Most downlights in this catalogue record >80; a good one records>84. This records above 92, which isnear the top of what LED lighting achieves.

Where that shows:

• Over a kitchen bench meat, greens, fruit and timber hold their colourinstead of going grey. It is the single most noticeable upgrade in a kitchen.
• On artwork, joinery and stone pigment, grain and veining read true.
• In a bathroom or dressing area skin looks healthy rather than washed out,and you can judge colour properly.

Our own web address for this page says CRI 90. The product records>92.

Five years and what that is worth knowing about

This module carries a five-year replacement warranty, where most fittings in thisrange carry three.

One correction to our own copy: the page said the warrantyprovides assurance that it will never need to be replaced. It does not. Afive-year warranty is a five-year term a genuinely good one, and among thelongest in this catalogue but no LED is permanent, and we would rather tell you the term thanimply something it does not cover.

Worth noting if you are comparing the MDL family: two of the three MDL-16D variantscarry five years and one is recorded at one. If you are looking at the 5000K version,ask us we believe that value is an error and have raised it with Telbix.

A 40-degree beam, and what to do with it

40 is a medium beam and the description’s wordoptimised is fair: it is wide enough not to spotlight andtight enough to keep light where you put it.

Compare the extremes in this catalogue: the POD 110 at 120 isa broad wash for general room lighting, and a 24 GU10 is a spot. At 40 theModule 16 sits between them, which makes it a genuinegeneral-purpose downlight: usable over a bench, and usable in a grid.

Spacing follows from the beam, and it is closer than a widedownlight’s. A 40 beam gives a defined pool, so fittings spaced asthough they were 120 will leave scallops between them.Tell us your ceiling height and the room, and we will work the layout out.

IP44, and the figure that is missing

IP44 protection against splashing water from any direction, sobathrooms outside the shower zone and laundries. WithCRI above 92, a bathroom is arguably where this fitting earns its money.

But no source records the cutout on arecessed downlight, and it is the first thing an electrician asks for. The fitting is63mm in diameter and 98mm deep, so the aperture will be smaller than 63,but we are not going to guess a hole size. Ask us before the ceiling iscut and we will confirm it with Telbix.

And no insulation rating is recorded on this variant, where the 5000Kversion records IC-4. Do not assume it may be covered by insulation ask us.

A small aperture, and a note on power factor

63mm diameter is small for a downlight mostdomestic downlights are 90 to 110mm. That makes the Module 16 adiscreet fitting: a run of them reads as small points in a ceilingrather than a row of holes, which suits a minimal or architectural interior.

Power factor above 0.9 mentioned on our page, andalmost nowhere else in this catalogue, so it is worth explaining. Power factor ishow efficiently a fitting draws the current it uses. A poor one (0.5) pulls morecurrent than its wattage suggests, which on a large number of downlights loads thecircuit harder than the arithmetic implies. Above 0.9 is good, and it matters on awhole-of-house run.

240V direct to mains no separate transformer.Dimmable: the type is not recorded, so tell us your dimmer and wewill confirm compatibility before you buy one. In aluminium, which carries theLED’s heat away and is the single thing that most determines how long a diode lasts.

Where it works

• Kitchen benches, artwork and joinery CRI>92.
• Bathrooms outside the shower zone, and laundries IP44.
• Minimal and architectural ceilings a 63mm aperture is discreet.
• Ask us for the cutout before the ceiling is cut.
• Space it closer than a wide-beam downlight, or you get scallops.

Questions

What is CRI above 92 worth?

It is near the top of what LED lighting achieves, and it is the reason to buy this. Most downlights here record >80 and a good one >84. Over a kitchen bench, meat, greens, fruit and timber hold their colour instead of going grey the single most noticeable upgrade in a kitchen. On artwork, joinery and stone, pigment and veining read true; in a bathroom, skin looks healthy rather than washed out.

Does the five-year warranty mean it never needs replacing?

No, and our page overstated it. Five years is a genuinely good term among the longest in this catalogue but no LED is permanent, and we would rather tell you the term than imply something it does not cover.

What size hole do I cut?

No source records it, on a recessed downlight and it is the first thing an electrician asks for. The fitting is 63mm across and 98 deep, so the aperture will be smaller than 63, but we will not guess a hole size. Ask us before the ceiling is cut.

Can it be covered by ceiling insulation?

Do not assume so. No insulation rating is recorded on this variant, where the 5000K version records IC-4. Ask us and we will confirm with Telbix.

How far apart should I space them?

Closer than a wide-beam downlight. A 40-degree beam gives a defined pool, so fittings spaced as though they were 120 degrees will leave scallops between them. Tell us your ceiling height and the room and we will work the layout out.

What is power factor, and does it matter?

It is how efficiently a fitting draws the current it uses. A poor one pulls more current than its wattage suggests, which on a large number of downlights loads the circuit harder than the arithmetic implies. Above 0.9 is good, and it matters on a whole-of-house run.

Can it go in a bathroom?

Outside the shower zone, yes IP44. And with CRI above 92, a bathroom is arguably where this fitting earns its money.
