The IBSR and the DH have tested the new self-reflective bombs and come to the same conclusions. Recently available on the net or in specialized stores, reflective material spray bombs have not yet invaded our cities. The Belgian Institute for Road Safety (BRSI) has conducted a study to determine the effectiveness of these products. The DH also performed tests.
To be effective, retro reflective paints must be visible when illuminated and otherwise invisible. “They can then become an alternative to fluorescent vests, considered impractical or cumbersome by some. Inversely, if they do not give the expected results, low users could have a false sense of security,” says the IBSR. As part of this survey, the BRSI tested paint samples on fabrics commonly worn outdoors and on building materials; and this in different weather conditions. At DH, we tested the textile bomb and checked its effectiveness on cotton in the dark.
“In view of the results obtained, the IBSR can not recommend the use of this type of retro reflective paint as an alternative to high visibility clothing. Although invisible paint, when properly applied, can improve the ability to be seen, the gain is much lower than that of traditional fluorescent jackets,” concludes the specialized institute.
First, the reflective effects are only noticeable at a distance of several meters. The spray is not very visible at three meters. Second, the product is certainly washable but is highly toxic and polluting, which is stated on the packaging. Third, to see the effect of the product, the packaging accurately makes a photo with flash. However, in our tests, we noted that the spray reflects much more flashlight than that of car headlights. Finally, the price of a bomb varies between 15 and 25 Euros depending on the volume (100 ml or 200 ml).
“If a properly approved garment is not available, the invisible retro reflective paint may be a good way to increase its visibility, but the user must be aware of its limited effect,” advises the BRSI. He welcomes the initiative and sees potential in this type of products.
