The new LTD-2500 features the exact same physical design as the Hydra 2500 v2 but specifically was designed to have just 2500 lumen white flood and a white 1500 lumen spot. This keeps the cost down for those who want a high quality dive or video light but do not need the various colors that the hydra line provides.
