For over 25 years LumiQuest has been refining the materials and design of our products to exacting photographic application and specifications. We have also developed the UltraStrap, the most secure non-adhesive mounting strap in the world.Each LumiQuest accessory is designed to accomplish different objectives under different circumstances. Several models can be used to photograph very different subjects that have similar light requirements. Usually one product would be preferable under certain circumstances … but sometimes not dramatically. And finally, some products would be a bad choice, useless or worse under some circumstances and absolutely perfect for others.
