Product Overview

The Twinstar Line consists of seven models, and the B series is the most budget-friendly line offered by the brand. This series is an ideal solution for those seeking a lightweight, slim LED aquarium light for a low-tech planted setup or a fish-only display. While it is easy on the wallet, it doesn't skimp on quality; the B Line is perfectly suited for growing low-light aquatic species such as Anubias, Bucephalandra, and Mosses.

Frequently Asked Questions

1. Is the Twinstar B Line strong enough to grow high-tech red stem plants?

The Twinstar B Line is optimized for low-to-medium light aquatic plants (such as Anubias, Bucephalandra, Java Fern, and mosses). For demanding, high-tech carpet plants or intense red stems requiring pressurized CO2 and high PAR, we recommend stepping up to the Twinstar E Line or S Line series.

2. Can I dim or set a timer schedule on the Twinstar B Line light?

The B Line light includes an on/off inline switch. To add sunrise/sunset ramping, dimming, or automated daily schedules, you can pair the fixture with an optional inline Twinstar Dimmer or smart outlet timer.

3. Will the Twinstar B Line fit rimless tanks with thick glass?

Models 20B through 90B V2 feature leg brackets compatible with glass panels up to 10mm thick. The largest model, 120B, features upgraded metal legs designed to accommodate heavy-duty rimless glass panels up to 15mm thick.

Q&A

Do you recommend the 30B or the 45B for a 16 inch tank? I am looking for a light for my Fluval Flex 15 gallon tank. Thank you!
Hello Nout, thank you for your question. We'd be happy to assist you with this. Depending on how planted your tank is, you may purchase either or. If you have more high tech plants in your tank, it is recommended to go with the Twinstar 45B to ensure all plants receive optimal lighting. If your tank is more within low tech style tank, the 30B will be sufficient! We hope this helps. If there is anything else we can assist you with, please email us at support@buceplant.com. Thank you, Team Buce Plant
I was gifted the 20B last Christmas and love it, but my rabbit chewed the cord on the adapter side (US plug) and I threw it away before replacing. Where can I purchase a replacement?
Hello Alex, Thank you for your question. Please feel free to reach out to our support team at support@buceplant.com and ask if we have any spare US plug available for the light. We are always happy to help! Kind Regards, -Team Buce Plant
Hi, I am planning on using this light with the 60U Tank or something similar. I know that I am going to have to find a custom lid solution as we have cats in the house. What are the dimensions of the CLIPS/Black ends that connect to the glass edge of the tank (length and width) so I can figure out cutouts.
Hi Liz, Thank you for your question. We'd be happy to help you with the size of the light stand so you can have a custom lid. Looks like its length is about 7 and 1/2cm and 1 and 1/2 inch in width. Hope this information helps. - Team Buce Plants
Does the 45B fit a UNS 40A?
Hello RJ, thank you for your question and interest. Yes, the Twinstar 45B lighting fixture can fit the UNS 40A tank. If you have any other questions or concerns, please email us at support@buceplant.com for further inquiry! Thank you, Team Buce Plant
I have a 180-gallon 6 feet long 24 inches wide and 24 deep witch light would be best for this tank
Hi Nick, thank you for your interest! Based on the dimensions of your tank, unfortunately, the Twinstar B lights would not be compatible. With a tank over 100+ gallons, it is recommended to go with a hanging light! As hanging lighting fixture will have the full coverage for your tank. Please feel free to email, support@buceplant.com, we'd be happy to provide further recommendations. Thank you, Team Buce Plant
