The Oren CTC915 is a 150mm surface-mounted LED downlight in black or whitesand 18W giving 1,680lm,switchable 2700K / 3000K / 4000K,CRI above 92, TRIAC dimmable, IP54.

No cutout. No ceiling void needed. It screws to the ceilingrather than dropping through a hole so it goes where a recessed downlight cannot:concrete ceilings, rendered soffits, shallow voids, rentals, heritage ceilings you must notcut, and under eaves outside.

The middle size, and the one that does most jobs

1,680 lumens from a 150mm body. That isenough to be a primary ceiling light in a bathroom, a laundry, a small bedroom or aporch on its own, where the 120mm version is better in a run. It is themost useful of the three for that reason: bright enough to work alone, small enoughnot to dominate.

The dimensions were published back to front

Our table gave Width 90mm, Height 150mm. It is150mm across and 90mm deep. The90mm is identical on all three Oren sizes while the other varies120 / 150 / 180 and a range of round downlights varies bydiameter, not by how far it hangs down. The model numbers agree:CTC912, CTC915, CTC918. Confirm with us before setting out a ceilinggrid.

CRI above 92

Most downlights here record CRI 80. The Oren recordsabove 92, and that shows on skin, timber, food and fabric at80, reds go slightly grey and timber flattens. At 93 lumens per watt while holdingCRI 92, it gives up almost nothing to get there.

IP54 splash-rated, so covered positions outside.Our page said it fits just about anywhereindoors or out.Under an eave, a verandah, a carport or a covered alfresco yes.An exposed soffit taking horizontal rain no.

36-degree beam

A focused beam, giving a defined pool rather than a wash. Space these closertogether than a wide-beam downlight, and remember that a focused beam from a 150mm fittingmounted on the surface sits 90mm lower than a recessed one whichslightly widens the pool at floor level.

TRIAC dimmable on an ordinary wall dimmer, andClassI earth required, at 0.53kg.

Where it works

• Bathrooms, laundries and small bedrooms bright enough alone.
• Concrete and shallow ceilings no cutout, no void.
• Porches, verandahs and carports.
• IP54 covered outdoor positions, not exposed.
• Confirm the diameter with us before setting out a grid.

Questions

Which Oren size should I choose?

This one, for most jobs. At 1,680lm it is bright enough to be the primary ceiling light in a bathroom, laundry, small bedroom or porch on its own, where the 120mm is better in a run and the 180mm is a bigger object on the ceiling.

Does it need a hole cut in the ceiling?

No it is surface-mounted, so it works on concrete ceilings, rendered soffits, shallow voids, rentals and heritage ceilings you must not cut, as well as under eaves outside.

How wide is it?

150mm across and 90mm deep. Our table had those reversed the 90mm is identical on all three Oren sizes while the other varies 120/150/180, and the model numbers CTC912/915/918 carry the same figures. Confirm with us before setting out a grid.

Can it go outside?

In covered positions. IP54 is protected against splashing, not jets or wind-driven rain under an eave, verandah or carport, yes; an exposed soffit, no.

Is CRI 92 worth it?

Over a bathroom mirror or a kitchen bench, yes. At CRI 80 reds go slightly grey and timber flattens; at 92 they do not and at 93lm/W this fitting gives up almost nothing to get there.

Can I dim it?

Yes TRIAC, on an ordinary wall dimmer.

Does surface mounting change the light?

Slightly. The fitting sits 90mm lower than a recessed one, which widens the pool a little at floor level. With a 36-degree beam that is worth allowing for in the spacing.
