All MC Rockets contain the “Next Generation” glow powder called strontium aluminate, which glows 10 times brighter and 10 times longer than the original (zinc sulphide.) I use only premium green glow, which is the brightest and glows longer than all other glow colours I tried – plus the fact that fish see different hues of green, and most of all, it works.
This premium glow powder – which not only absorbs light, but then re-emits it slowly over time – is activated by a light source high in UV, such as black light or sunlight. Time required for a full charge (Glow time 4-5 hours, probably longer):
Sunlight – 5 min.
Black light – 10 min.
Halogen – 10-15 min.
For the early risers, a double-bulb 12V portable black light (found at Canadian Tire in the car accessory department) works well. We use a box lined with tinfoil, with a light at the top and one at the bottom. Do not place a Rocket directly on top of any plastic lens as it could have a chemical reaction, dulling the lens. Wrap the lens a couple of times with cling-free clear food wrap. A simple fix.
All Rockets contain glow on the back side, while the single digit colour numbers have glow throughout (Ultra Glow). Simply apply a UV light source to the back side, as well as the front on the Ultra Glows. They will glow for 4-5 hours – probably longer with the brightness decreasing as time elapses. And it can be charged hundreds of times without losing its brightness. Just remember: “IF IT DON’T GLOW, IT DON’T GO.”
