These are not two grades of the same product. A silicone neon is a finished light \u2014 strip, diffusion, and seal made as one body. An aluminum profile is a housing: you choose the section, put a strip inside, and add a cover. The difference that decides most projects is not brightness or appearance. The difference is that a neon strip can be pulled out and replaced, while a <\/strong>profile strip usually cannot.<\/strong><\/p>\n\n\n\n

\"Section
A profile is a housing. The metal is the heat path, and the strip is added to it.<\/figcaption><\/figure>\n\n\n\n

Which one handles heat?<\/h2>\n\n\n\n

The aluminum one, by a wide margin, and this is the constraint that sets the power ceiling.<\/p>\n\n\n\n

A silicone neon wraps the strip in a material that conducts heat poorly. That is fine at moderate output \u2014 our neon range is built for the loads it is sold at \u2014 but it means the format does not scale upward. Ask a neon to carry a high-output strip and the heat has nowhere to go.<\/p>\n\n\n\n

An aluminum profile does the opposite: the strip sits against metal that spreads heat into a body with surface area. This is why the same strip that is comfortable in a deep profile may be marginal inside a 10 mm silicone sleeve.<\/p>\n\n\n\n

The practical threshold that comes up repeatedly is around 12 W\/m.<\/strong> Below it, both formats work and the choice is about shape and exposure. Above it, the aluminum profile is the only honest answer.<\/p>\n\n\n\n

Which one can you repair?<\/h2>\n\n\n\n

This is the difference buyers ask about last and regret first.<\/p>\n\n\n\n

A silicone neon is a sleeve. The strip inside can be pulled out \u2014 at any point in the future, without touching the fixing \u2014 and replaced or upgraded. The body stays where it is.<\/p>\n\n\n\n

An aluminum profile with an adhered strip is effectively permanent. The adhesive is designed not to let go, and removing a strip from a narrow channel usually means scraping it out, damaging the cover groove, or both. On a recessed or plastered-in body, that is a ceiling repair rather than a strip swap.<\/p>\n\n\n\n

So the question is not hypothetical: will this run ever need a new strip?<\/strong> If the answer is yes \u2014 a commercial space on a ten-year horizon, a color-temperature change, a driver upgrade requiring different voltage \u2014 the neon has an advantage that has nothing to do with light.<\/p>\n\n\n\n

\"A
3D bend \u2014 the format that follows a curve in two planes, which extrusion never does.<\/figcaption><\/figure>\n\n\n\n

What about curves?<\/h2>\n\n\n\n

Only the neon bends. Extruded aluminum does not, and every change of direction in a profile run needs a joint: a miter cut, a corner piece, or a gap.<\/p>\n\n\n\n

\"Flexible
HL-1515B1 \u2014 a flexible body, for when the run curves but the light still needs aluminum.<\/figcaption><\/figure>\n\n\n\n

A neon follows a radius continuously, in one plane, with no seam at the bend. That single property is why signage, logo outlines, and curved reveals are almost always neon.<\/p>\n\n\n\n

If a curve must be aluminum, the options are a flexible profile \u2014 we carry five, with a silicone body and an aluminum insert \u2014 or a segmented approach: short straight lengths mitered around the arc, which leaves visible joints unless the radius is generous.<\/p>\n\n\n\n

What about water?<\/h2>\n\n\n\n

A neon is sealed at manufacture. Our neon range runs from IP65 to IP68, and the IP68 models are tested as complete assemblies, not as components.<\/p>\n\n\n\n

An aluminum profile is an open channel. Its water resistance is created on site \u2014 cover seated, both ends capped, cable entry glanded \u2014 and it is only as good as that work. We do not claim an IP rating for any bare profile<\/strong>, because the rating belongs to the assembly.<\/p>\n\n\n\n

For an exposed outdoor line, that difference matters: the neon arrives with the seal already made and tested; the profile arrives with the seal still to be built.<\/p>\n\n\n\n

Where does each one fail?<\/h2>\n\n\n\n

Neon fails on:<\/strong> high output, long straight runs where the outlay is hard to justify, and any detail where a 10\u201330 mm round body is visually too heavy.<\/p>\n\n\n\n

A profile fails on:<\/strong> curves, exposed wet locations where the sealing work is not controlled, and any run where the strip will need replacing inside a narrow channel.<\/p>\n\n\n\n

Neither failure is a defect. Both are the format showing its shape.<\/p>\n\n\n\n

What does a mixed installation look like?<\/h2>\n\n\n\n

Mixing the two is common, and it works, provided the transition is designed rather than improvised.<\/p>\n\n\n\n

Three details decide whether the joint reads as intentional:<\/p>\n\n\n\n

Body size.<\/strong> A 6 mm neon and a 15 mm profile do not meet cleanly. Either match the visual weight, or make the change deliberate \u2014 a visible step at a corner or a change of plane, where the eye accepts it as two systems.<\/p>\n\n\n\n

Light level.<\/strong> Neon diffusion and profile output rarely match at the same strip wattage. Where the two meet, expect a step unless the neon run uses a brighter strip or the profile run uses a denser one.<\/p>\n\n\n\n

Where the joint sits<\/strong>,\u00a0put it at a corner, a change of surface, or behind a return \u2014 anywhere the eye already expects a break. A joint in the middle of a straight run is the one that looks like a mistake.<\/p>\n\n\n\n

The pattern that works most often: neon on the curves and the exposed outdoor section, profile on the straight interior runs, with the change happening at a corner where both are already terminating.<\/p>\n\n\n\n

How do you decide?<\/h2>\n\n\n\n

Three questions, in order:<\/p>\n\n\n\n
