With 11000 fixture Lumens and a 1 in (25 mm) profile head, the 3010TH is the ideal underwater light for transom mount applications. Suitable for all hull types up to and over 65 ft (20 m) using 2-6 lights with spacing of 3 to 5 ft (1 to 1.5 m). For metal hulls, choose the Delrin Isolation Sleeve accessory. Deutsch plug and play quick connectors make this light a quick fit. Maintenance is easy; just wipe away marine growth from its scratch resistant Titanium™ glass lens. Three super bright LED color options, or for an even brighter light choose 3010TH HD Gen2. For a light with a lower profile head for hull mount applications, or that can be exchanged without hauling, choose from our XFM models. For a light with color change capabilities choose from our Colors models.
