Front bend (also called top bend) arches the profile forward and backward — it bends in the vertical plane. Use it for cove ceilings, wall outlines, staircase edges, and mirror frames where the curve runs along one flat surface.

Side bend curves the profile left and right — it bends in the horizontal plane. Use it for letters, logos, signage, arched doorways, column wraps, and any shape where the curve is traced from above.

Getting this wrong means the profile physically cannot follow your intended shape. When in doubt, send us a sketch on WhatsApp.

No — the 24V driver is not included and must be purchased separately. The profile is sold as 5m rolls only. You need a 24V DC driver sized to your total strip load plus 25% headroom.

Use the Power Calculator on this page to find the correct driver size for your profile and run length. Chronos 24V drivers are available separately in sizes from 40W to 400W.

The formula is: (Watts per metre × Total length) × 1.25

The 1.25 factor is a 25% safety headroom — running a driver at 100% load continuously shortens its lifespan significantly.

Example: 8×16mm profile at 10W/m, 8m run = 80W × 1.25 = 100W driver minimum.

Use the interactive Power Calculator on this page — select your profile size and drag the length slider to get an instant recommendation.

Yes — every profile can be cut to length at the marked cut points only. Cut points are printed on the profile every 25mm (smaller sizes) or 50mm (larger sizes).

Use sharp scissors or a flush-cut tool for a clean edge. Never cut between the marked points — it will sever the LED circuit and that section will not light.

After cutting, seal the open end with an end cap to maintain the IP65 rating.

Maximum run length varies by profile size — smaller profiles can run up to 10m from one power input, while larger profiles (18×26mm, 20×20mm) should not exceed 5m per injection point due to higher current draw.

If your total run is longer than the maximum, you need power injection points — additional driver connections mid-run. The Power Calculator on this page tells you exactly how many injection points you need based on your profile size and run length.

Use a joining connector designed for your specific profile size — the connector slides onto the cut ends of both rolls and provides both a mechanical joint and an electrical connection.

Important: ensure both rolls are cut clean at their respective cut marks before joining. If the total combined length exceeds the maximum single run, you will also need a mid-run driver injection at the join point.

Profile joining connectors are available in our connectors collection.

Yes — all Chronos silicone neon profiles are rated IP65 as standard, which means they are dust-tight and protected against water jets from any direction. IP65 is suitable for covered outdoor locations: under eaves, on covered balconies, outdoor signage sheltered from direct rain.

For fully exposed outdoor installations — building facades, uncovered outdoor signage, locations where the profile faces direct rain — use the IP67-rated 18×26mm or 20×20mm profiles, which are rated for temporary immersion.

Do not use IP20-rated profile outdoors under any circumstances.

Yes, with the right IP rating for your zone:

• Mirror frame and vanity counter (Zone 2 — more than 60cm from water source): IP65 is sufficient
• Near the shower or bath (Zone 1): IP65 minimum; IP67 strongly recommended
• Inside the shower enclosure (Zone 0): Do not install LED profile inside the shower — this is not safe at any IP rating for a DIY installation

All Chronos silicone neon profiles are IP65 rated. Use IP67 profiles near the shower.

All Chronos silicone neon profiles are available in:

• 2700K — Warm white (amber-toned, bedroom and hospitality ambience)
• 3000K — Soft warm white (most popular for living spaces)
• 4000K — Natural white (kitchen, bathroom, retail)
• 6500K — Cool daylight (outdoor signage, commercial facades)
• RGB — Full colour changing with compatible controller

CRI is 90+ on all white variants, verified per production batch.

For most residential cove ceilings, 8×16mm is the most popular choice — it produces a visible glow without overpowering a room and has a good minimum bend radius for corner transitions.

If your cove is large (ceiling height 3m+, room larger than 25sqm) or you want a bolder effect visible from across the room, step up to 10×20mm.

For a subtle accent effect in a small room or low ceiling, 6×12mm is sufficient.

Yes — and it becomes more obvious over time. Silicone is UV-stable and heat-resistant: it does not yellow, crack, or harden, so the glow colour remains consistent year after year.

PVC neon profile (sold cheaply as a substitute) yellows from heat within 1–3 years. The yellow tint gradually distorts warm white into an orange-tinged glow and cool white into a greenish cast. The PVC also becomes brittle and may crack at bend points.

Chronos profiles are extruded silicone — not PVC — and carry a 2-year warranty.

Yes — all Chronos silicone neon profiles are dimmable when used with a compatible 24V dimmable driver and a dimmer controller (touch, rotary, or smart WiFi).

The profile itself has no dimming circuitry — dimming is handled entirely by the driver and controller. Pair with a trailing-edge or 0–10V dimmable driver for smoothest performance. Leading-edge (TRIAC) dimmers may cause flicker at low brightness levels.

Minimum bend radius varies by profile size and bend direction:

• 4×10mm: ~40mm
• 6×12mm: ~45mm
• 8×16mm: ~50mm
• 10×20mm and above: 55–90mm (larger profiles need a wider turning radius)

Forcing a tighter bend than the minimum will cause the silicone to kink and may crack the internal LED circuit. For very tight letter forms (e.g. a small 'O' or 'S'), use the smallest available profile and plan your letter dimensions around the bend radius.
