Start with the throw distance
Ask where the fixture will physically sit before asking what it should cost. On a logo light projector the throw distance sets the lens, the lens sets the image size, and only then does wattage become a meaningful question. Buyers who start with the power figure usually end up with a unit that is either wasted on a short throw or hopeless on a long one.
- Distance from the realistic mounting point to the centre of the target surface
- Image width you actually need, measured on the wall
- Whether the surface is flat, matte and square to the beam
- Any obstacle in the beam path — signage, foliage, display stands
Match output to the ambient light
Match the output to the darkest hour you care about, not the brightest. If the logo light projector only has to work after sunset, 15 W may be generous; if it has to hold up against a shop window at 4pm, you are looking at the top of the 15–120 W range and still managing expectations. Overbuying power to solve an ambient light problem is the most expensive way to fix it.
The optics decide what you can actually adjust
Ask two questions about the lens: what is the throw ratio range, and can focus be locked. A logo light projector with a 3:1 zoom will cover 3 to 18 m from the same bracket, but only if the focus mechanism holds its setting once the housing is warm and the site has been vibrating for a month.
What your artwork forces you to buy
Your artwork decides the gobo material, not the other way round. A metal gobo handles fine strokes, gradients and photographic halftones that a metal stencil simply cannot hold, but it costs more and needs a little more care in handling. If the design is a solid single-colour mark with no fine detail, metal is cheaper and effectively unbreakable; if it has thin script or a gradient, glass is the only honest answer.
Ingress rating and mounting environment
The ingress rating is a statement about where the unit can live, not how good it is. IP44 on a logo light projector means it will cope with the conditions it was tested for — driving rain, dust, or in the case of indoor ratings, nothing more than a wipe-down. If the install is under a soffit that only sees wind-blown rain, an indoor-rated unit may be fine; if it is exposed on a hair salon, IP44 is the floor, not the target.
The five lines that get an accurate quote
Before you send the enquiry, walk the site once with a tape measure and a phone camera. Throw distance, surface colour, the position of power, and a photo of the ambient light at the relevant hour will get you an accurate logo light projector recommendation on the first reply — and they are all things you will need on install day anyway.
