The Domus KEY-PAR38 is a 16W LED reflector globe in thePAR38 shape on an E27 base, IP44, with a36 beam and a frosted lens, in 3000K or5000K.

IP44 on a globe is unusual, and it is the reason to choose thisone. Almost every lamp in this catalogue is IP20 dry interiors, inside a fitting thatprovides its own protection.

This one is rated in its own right. That makes it a lamp for an open exteriorholder: a batten holder under an eave, a bulkhead fitting, a security floodlight housing, agarden spotlight that takes an E27. IP44 is splash protection, not immersion acovered position, not a hosed one, and the fitting’s own rating still applies.

The base is E27 the large screw base. Our record does not list a base atall, which is worth checking against your holder.

What PAR38 means and why it matters here

• PAR38 is a reflector lamp the reflector is built into the globe, so the beamis shaped by the lamp rather than by the fitting.
• That is what lets it work in a plain open holder: a bare batten holder under aneave will throw a proper 36 beam with this lamp in it, where an ordinary globe would spill light inevery direction.
• 120131mm it is a largelamp. Check it against the fitting’s internal clearance and against any shade or guard.
• The frosted lens softens the edge of the beam and hides the LED array, so it does notread as a bright point when looked at directly.

The 36 beam

• A medium beam genuinely directional. At three metres it lights a circle ofroughly two metres across.
• Right for lighting a specific thing: a doorway, a gate, a parking bay, a shedentrance, a piece of planting.
• Wrong for lighting an area. If you want a whole yard covered, this will leave abright circle and dark edges ask us for a floodlight instead.
• 1,350lm at 3000K, 1,400lm at 5000K from16W.

It is not dimmable

The datasheet is explicit, and this is worth flagging because a 16W lamp on a domestic circuit isexactly the sort people assume will dim.

A non-dimmable lamp on a dimmed circuit does not simply stay bright it canflicker, buzz, or fail early. Check the circuit before ordering, and tell us if it isdimmed so we can suggest an alternative.

Choosing between the two colours

• 3000K 1,350lm. A house entry, a gate, a garden, a carport. Warmlight outdoors reads as light.
• 5000K 1,400lm. Marginally brighter, and much colder. Security,sheds, workshops and parking areas.
• There is no 4000K in this lamp, so it is a two-way choice rather than thethree most of this catalogue offers.

What it replaces

• Roughly a 120W halogen PAR38 at about an eighth of the power, and without theheat which matters in a sealed exterior fitting.
• 30,000hours, below the 50,000 of the GU10 and MR16 lamps in this range butrespectable for a high-output reflector.
• CRI 80, SMD.

Where it works

• Open exterior E27 holders batten holders under an eave, bulkheads, spotlight housings.
• Lighting something specific: a doorway, gate, parking bay, shed entrance, planting.
• Damp indoor positions a garage, a shed, a laundry.
• Not on a dimmed circuit.
• Not for lighting a whole area 36 leaves dark edges.
• Check the fitting’s clearance 120 131mm is a large lamp.

Questions

What base does it have?

E27 the large screw base. Worth checking against your holder, because our product record does not list a base at all; the figure comes from the datasheet. E27 is the common large screw fitting, not the small E14.

Can I use it in an open exterior fitting?

Yes, and that is the main reason to choose it. IP44 on a globe is unusual almost every lamp in this catalogue is IP20, meaning dry interiors inside a fitting that provides its own protection. This one is rated in its own right, so it suits a batten holder under an eave, a bulkhead, or a spotlight housing. IP44 is splash protection rather than immersion, so a covered position rather than a hosed one, and the fitting’s own rating still applies.

Can I dim it?

No, and it is worth checking your circuit before ordering, because a 16W lamp on a domestic circuit is exactly the sort people assume will dim. A non-dimmable lamp on a dimmed circuit does not simply stay bright it can flicker, buzz or fail early. Tell us if the circuit is dimmed and we will suggest an alternative.

How wide is the beam?

36, which is a medium beam and genuinely directional at three metres it lights a circle of roughly two metres across. That suits lighting a specific thing: a doorway, a gate, a parking bay, a shed entrance, a piece of planting. If you want a whole yard covered it will leave a bright circle and dark edges, and a floodlight is the right answer instead.

What does it replace?

Roughly a 120W halogen PAR38, at about an eighth of the power and without the heat which matters in a sealed exterior fitting where a halogen has nowhere to shed it. Its rated life is 30,000 hours, below the 50,000 of the GU10 and MR16 lamps in this range but respectable for a high-output reflector.

Will it fit my fitting?

Check the clearance at 120 131mm this is a large lamp, noticeably bigger than an ordinary globe. Measure the internal space and any shade or guard before ordering, particularly in a bulkhead or a spotlight housing where the lamp sits close to the cover.

Which colour should I choose?

3000K for a house entry, a gate, a garden or a carport warm light outdoors reads as light rather than as security. 5000K for sheds, workshops, security and parking areas; it is marginally brighter at 1,400 lumens and much colder. There is no 4000K in this lamp, so it is a two-way choice.
