Lighting is one of the most overlooked factors when painting cars. Even with the best spray gun and paint, poor lighting can ruin a job. Shadows, uneven illumination, or glare make it hard to see coverage, metallic flake orientation, and wetness of the paint. That’s why a dedicated spray gun light — a small, bright LED light mounted directly on the spray gun — is a game changer. It lets you clearly see the paint fan as you spray, helping you achieve smooth, even coats with fewer mistakes.

Buyer’s Guide: What to Look for in a Spray Gun Light

- Mounting style: Clip-on vs integrated designs. Clip-ons are universal, integrated options are more seamless.

- Durability: Must withstand overspray, solvents, and constant use in a paint booth or garage.
- Compatibility: Ensure the light fits your gun type (HVLP, LVLP, gravity feed, etc.).

FAQ
- Do I really need a spray gun light?
Yes. Proper lighting shows coverage, reduces mistakes, and ensures even metallic distribution — especially in dim garages. - What color light is best?
Neutral white (around 4000–5000K) is ideal because it shows true paint color without distortion. - Can I use a regular work light instead?
You can, but overhead or side lights cast shadows. A spray gun light moves with your gun, showing the fan pattern directly. - Are clip-on lights universal?
Most clip-on models fit standard gravity-feed HVLP/LVLP spray guns, but always check compatibility. - How do I keep lights clean from overspray?
Wipe with solvent-safe cloths after each session and use protective film covers if included.
