LED replacements for 9″,12″, 18″ and 21″ florescent tubes!
Our new LED clusters come mounted on their own aluminum heat-transfer enclosed in a polycarbonate lens. We offer them in natural-looking, “warm-white” or the super-bright “cool-white” which looks more like a florescent. These bulbs feature our Constant-Current Chipset so work on either 12V or 24V (10-30Volt range) and fit into your existing fixtures. However they do require a slight modification to by-pass the existing ballast. It is a simple modification requiring no more than some wire cutters and a couple of butt connectors.
Cool White is fluorescent white (6150K), Warm White is incandescent white (2950K). Red preserves your night vision.
These are not for 120VAC home use.

Shipping & lead times
Shipping & lead times
We're a small team of boaters and we pack orders within 1–5 business days (no weekend or holiday packing). You'll get an email with tracking as soon as a label goes on your box.
Specialty items — fire extinguishers (dangerous goods) and low-stock or built-to-order gear — can take longer; the product description will say so. On a tight timeline or meeting your boat somewhere specific? Contact us and we’ll work out the fastest way to get gear to you.
International orders ship DDU: local duties, taxes, and customs fees are the buyer’s responsibility. Full details in our shipping policy.
Returns & refunds
Returns & refunds
30-day returns from the date of purchase. Items must be unused, in the original packaging with all cables and accessories, with proof of purchase.
Contact us before shipping anything back — we’ll send the return form that must accompany your return. Fire extinguisher and lithium battery items carry a $15 administrative fee on returns.

Everyone here is a current or past cruiser — we’ve docked short-handed, re-rigged at anchor, and chased 12V gremlins too. Not sure this is the right fit for your boat? Send us your question before you order and we’ll give you a straight answer.
Check fit before ordering
- Base and pins: match the socket, contact count, pin position, orientation, and spacing to the lamp being replaced.
- Electrical fit: verify the DC voltage range, polarity requirements, and compatibility with existing dimmers.
- Physical clearance: compare the full bulb diameter, height, pin length, lens, and reflector clearance.
- Light output: choose the intended color, temperature, beam pattern, and navigation or cabin-light use.
