The Halon ST1 is a 24 V exterior LED step light in solid brass or 316 stainless steel with glass — 1 W giving 65 lm at 3000 K, CRI above 90, IP67 — in antique brass, natural brass or stainless steel. It runs on 24 volts, so it needs a transformer — and we stock them. A 240 V-to-24 V supply is required and no Telbix fitting in this range records one as supplied. We sell an outdoor 24 V transformer in 60 W and 200 W, both IP68. At 1 W each these are the cheapest fittings in the range to run: a 60 W transformer would drive dozens. Tell us how many steps you are lighting and we will size it. IP67 on a step light — and that is the reason to choose it IP67 means dust-tight and rated for temporary immersion. Not splashing, not jets — submersion. On a step that matters more than it sounds: water runs down stairs and pools against the riser, and a fitting set into that riser will sit in standing water after heavy rain. Compare the Jora step light in this range, which is IP54 — splash-rated only, and suited to covered steps. The Halon at IP67 is rated for fully exposed steps that take run-off. If your stairs are outside and uncovered, this is the one. Solid brass or 316 marine stainless Our record lists “Glass” alone. The body is solid brass or 316 stainless steel — and set into a wet riser, taking run-off and cleaning, that is the only sensible construction. 316 is the marine grade, with added molybdenum to resist salt; brass weathers rather than corrodes. Three finishes — and one of them ages Antique brass starts dark and stays close to it. Natural brass is unlacquered and will patina to a soft brown-gold. 316 stainless stays silver. On a run of steps that decision compounds — you are choosing whether the whole flight changes together over the years. Two cutouts, and it must be decided before the concrete 46 mm with the canister, 35 mm without. The canister is the sleeve set into the step; whether you use it decides the hole size. The face is 53 mm by 51 mm and it weighs 0.35 kg. Confirm with your builder which arrangement they are using before the steps are poured or the treads cut — it cannot be changed afterwards. 65 lumens, and that is correct for a step A step light should show you the edge of a tread without dazzling you on the way down. 65 lm is deliberately small, and the CRI above 90 is what makes it worth having: stone, timber and concrete keep their real colour rather than going grey, so you see the step as it actually is. Where it works Fully exposed exterior steps — IP67 handles run-off and pooling. Deck and concrete risers. Coastal installations — 316 stainless or solid brass. ⚠ Confirm the cutout with your builder before the steps are poured. ⚠ Needs a 24 V transformer — we stock 60 W and 200 W. Specifying it 53 mm by 51 mm face, cutout 46 mm with the canister or 35 mm without, 0.35 kg, tail 1,000 mm, in solid brass or 316 stainless steel with glass. Integrated 1 W LED giving 65 lm at 3000 K, included, CRI >90, not dimmable. 24 V — a transformer is required and none is supplied; we stock 60 W and 200 W. Class III — low voltage, IP67 — dust-tight and rated for temporary immersion. Warranty is three years, as a replacement warranty. Supplied and supported by Lights For You. Questions Can it go on uncovered steps?Yes — that is the reason to choose it. IP67 is dust-tight and rated for temporary immersion, which matters on a step because water runs down stairs and pools against the riser. The Jora step light in this range is IP54, splash-rated only, and suited to covered steps. Does it connect to a normal circuit?No — 24 volts, so a 240 V-to-24 V transformer is required and none is supplied. We stock 60 W and 200 W outdoor transformers. At 1 W each these are the cheapest fittings here to run — a 60 W transformer would drive dozens. What cutout does it need?46 mm with the canister, 35 mm without. The canister is the sleeve set into the step, and whether you use it decides the hole size. Confirm with your builder before the steps are poured or the treads cut — it cannot be changed afterwards. What is it made of?Solid brass or 316 stainless steel with glass. Our record lists “Glass” alone. Set into a wet riser taking run-off and cleaning, that is the only sensible construction. Which finish should I choose?Antique brass starts dark and stays close to it; natural brass is unlacquered and patinas to a soft brown-gold; 316 stainless stays silver. On a run of steps the decision compounds — you are choosing whether the whole flight changes together over the years. Is 65 lumens enough?For a step, yes, and more would be worse — it should show the edge of a tread without dazzling you on the way down. The CRI above 90 is what makes it worth having: stone, timber and concrete keep their real colour rather than going grey. How does it compare to the Halon inground light?Same family, same 24 V and IP67, same materials. The inground is 45 mm round at 110 lm for setting into a surface you walk over; this step light is 53 by 51 mm at 65 lm for setting into a riser.
