Frequently Asked Questions

1. How does the Twinstar S Series compare to the C Series and E Series?

The S Series is Twinstar's flagship high-output line designed specifically for high-tech planted aquariums with CO2 injection. It provides significantly higher PAR and lumen output than the C and E Series, allowing you to grow demanding carpet plants and achieve maximum red coloration in stem plants.

2. Can I use the Twinstar S Series on a low-tech tank without CO2?

While possible, the S Series produces very high light intensity. If used on a low-tech setup without CO2 or proper nutrient management, you may experience algae growth unless you reduce the daily lighting photoperiod or pair it with an inline dimmer.

3. Are the metal mounting legs adjustable?

The standard S Series fixed model features solid metal legs designed to fit flush over the precise tank lengths listed in the sizing chart. Be sure to double-check your aquarium glass length and rim width prior to ordering.

    Twinstar S series

    "Excellent Twinstar light! This is the best one I have tried. It makes my aquascape pop"

    — DAVID B. (5/5)

    No light control without 2nd item

    "Unfortunate you have to pay an additional $20-40 to have access to basic light controls for such a premium item"

    — Xaviel M. (4/5)

    Highly recommend, satisfaction guaranteed

    "This light fixture was recommended by MJ Aquascaping as top tier for aquariums. With his knowledge and experience with different lighting, out of all the options, I chose what I thought would be a great purchase, which indeed it is. Being new to aquascaping, I wanted to just front the cost of a really good light fixture instead of having to purchase other products that would eventually need to be replaced, as well as not providing all of the amenities that this product has. It provides optimum lighting for my tank and I am very pleased with the aesthetic design. Shipping was fast and arrived sooner than I thought and the item was packaged well. My first purchase from you guys far exceeded my expections. Bravo BUCEPLANT."

    — Laccey X. (5/5)

    This light is bright! Much

    "This light is bright! Much more than the E series. I was having trouble with a few plants with the E placed on a UNS 45T. Hopefully the S will fix that. The S light makes my red plants more red somehow. Won't complain. Lots of pearling already."

    — Andrew S. (5/5)

    So amazing

    "I absolutely love this light. It does come with a dinner so don’t make the mistake like me and order one. It is bright and reds really really pop."

    — Spencer A. (5/5)

    Literally Amazing

    "OK, so this is my first Twinstar light review. I have previously owned a lot of LED lights from Finnex and Fluval, and let me say.... this is an intense step up from all of them. It makes the red plants pop. My plants are pearling like crazy and growing at an incredibly high rate. The light works well on a timer and is built amazingly. Here are some things that I feel you should be aware of when buying this. 1.) It is bright - It is the most brilliant aquarium light I have ever owned - and it sits up higher than ones that are flush with the tank - this means that if you have a chair next to you, you will have a bright light in your face. I wish these lights came with " side shades" that attach to the front and sides of the fixture to keep the light from diffusing out everywhere. 2.) Unlike in the UK, you do not get the dimmer and timer that comes with it for FREE - I find this annoying. However, I do not use it as it is connected to a smart timer. 3.) Mine did not come with the fancy legs pictured in the image - they went with the adjustable ones, which I don't think look as good. This frustrated me because the idea didn't have these. My opinion is this - if you are going for a high-end and high-tech setup, then this light is a no-brainer - it is amazing, it looks good, and it works incredibly well - It will make your fish look stunning! If you are not doing CO2 injection and have high-light plants, I would go for a lower-setting light such as the E series, as this light appears to be equivalent to the sun."

    — Parker H. (5/5)

    Great lights. All my plants

    "Great lights. All my plants are growing wonderfully."

    — Zheng H. (5/5)

    High powered

    "Received as advertised in height, looks, and output. This light has some serious kick to it! Highly recommend."

    — Tim P. (5/5)

    Great light.

    "Love the light, it fits perfectly."

    — Cael C. (5/5)

    Quality Aquarium Lighting

    "I purchased a couple of aquarium light fixtures, and the twin star LED series are by far the highest quality aquarium lighting hardware that I have come across. It has a sleek, minimalist modern style and a platinum color finish. I would highly recommend picking up the dimmer with lighting fixture. This is hard to come by but it’s worth the investment. This is not your typical cheap equipment. There are much more affordable options I just like the look and engineering behind this product."

    — Marvin U. (5/5)

    Q&A

    Are the legs replaceable? I'm considering this light, but I do not like the solid colored legs for putting on a rimless tank. I like the look of the clear legs much better.
    Hi Tracy, Thank you for your question. The legs on the Twinstar LED S Series are not designed to be replaced. Best regards, Team Buce Plant
    Lost my power adapter can someone please post the power supply stats, voltage and amp output. Thanks
    Hello Jay, thank you for your question. Please email us at support@buceplant.com for further inquiry on this! Our team would be happy to assist you forward. Thank you, Team Buce Plant
    Will the 450S fit my 45cm tank with 6mm glass? I know it states 5mm but looks like there is a little extra space on the legs in the pictures.
    Hi Kaleb, Thank you for your question. Based on the details you provided the light should be able to work with the dimension of your tank. However, please note that it might not sit flush on the rim of your tanks as the measurement may be just a little off, but should work! Best Regards, -Team Buce Plant
    Is this version 3 of the light that is being sold?
