Second I've become used to treating my lights like dirt knowing that they have some water resistance, I dont want to risk it with these lights, so everytime I do tank maintenace I remove them well away, again loose brackets doesnt help with this. Third thing its the length is something like 27cm. It may not seem like much but 27cm light strip on a 38cm tank feels not adequate. I think its a case of buy cheap pay twice. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Pay more, get more *by B***R on Reviewed in the United Kingdom on 15 June 2019* You pay a bit more but get a lot more in return, including more light and better controls, especially the blue light feature. Remote control? Who are you kidding? ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Adds real depth to the tank. *by M***N on Reviewed in the United Kingdom on 2 September 2019* Easy to set up, the RGB lights add real depth to the tank. We can see more of our fish now this light is in place, the colour definition is great.I tend not to use the blue light only mode at night (I just get Alexa to turn the light off!) but it is a good shade of blue. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/65564107-mainlicht-aquarium-light-with-rgb-and-blue-led-for-11](https://www.desertcart.sk/products/65564107-mainlicht-aquarium-light-with-rgb-and-blue-led-for-11) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-30*
