Upgraded version is great! *by on Reviewed in the United States May 29, 2025* UPDATE #2 I upgraded my original review from 2-5 starsThe customer service has been excellent from this seller. After I got my massive algae outbreak under control(see below) I purchased the upgraded version of this light which now has the ability to change brightness and color in 24/7 mode. The only way to tell if you receive the upgraded version ( because the old and new are currently mixed together at the warehouse) is to look at page 10 of the manual. If the top line on the page says time, color, brightness, you received the newer version. There is a battery backup in the control that saves current settings in case of a power outage which is a great feature. There are helpful programming videos explaining how to set up the controls, so it's not as complicated as it initially seemed. I am currently running 2 different sizes of this light on 2 separate tanks and have been very pleased with the newer version. My plants are doing great and there's no algae outbreak in sight. I will buy more in the future.ORIGINAL REVIEW. The controls are quite complicated to program on this very bright light. The biggest problem that I have experienced is that there is no way to dim the light intensity level when on 24/7 mode, which resulted in a MASSIVE hair algae outbreak that covered all of my plants, glass and rocks in a surprisingly short period of time. I have pulled out an entire tank full of live plants 3 times and dipped them in diluted peroxide followed by dosing of liquid carbon to try to keep them from dying due to algae suffocation. I have also removed all of the hardscape and scrubbed it down to remove the blanket of algae covering it as well. I have been doing 50% water changes every 3 days for the past 4 weeks because the algae returns so rapidly. I have even done total blackouts which helped, but once I turned the light back on for 2 hours per day, for the plants survival, poof! the algae returned with a vengeance. I have become a slave to my aquarium, spending many hours per week battling this scourge. It will be a miracle if my plants survive, because they are all currently melting. Once this algae sets in it seems to be very difficult to overcome. I finally resorted to replacing this high intensity light with the old kit light that came with my aquarium and so far the algae has not returned.UPDATE #1: Customer service reached out to me several hours after posting this review and offered me an upgraded replacement that allows brightness adjustment in 24/7 mode or a refund. Customer service has been excellent. I am willing to try the upgraded light, since I was happy with the quality. Regarding the difficult programming of the light schedule, customer service sent me more detailed directions and is also willing to help program specific times if needed. This company has been very willing to stand behind their product, which I really appreciate. I will be happy to try the upgraded version. ### ⭐⭐⭐⭐⭐ Light does in fact grow plants. *by on Reviewed in the United States July 25, 2026* The light is great. It’s doing well on the 29 gallon planted tank I purchased it for. It has enough PAR to actually reach the substrate which is approximately 15 inches down in an 18 inch deep tank. I’m growing easy to medium care plants along with some floaters like “frogbite” and after only a couple days the plants are really looking great and more vibrant. Heat is minimal and timer was easy to set up. Anyone who says differently probably didn’t even bother to look at the instructions or is the type of people that should be supervised and wearing a helmet at all times. ### ⭐⭐⭐⭐⭐ Fantastic fully programmable light with battery backup. *by on Reviewed in the United States January 26, 2026* I have this light on a 40g Marineland breeder tank that has a 36”x18” footprint. This pic was taken with the light set at 10% brightness on full spectrum. Without a doubt, if you want to grow plants this is an absolute powerhouse.My Cichlid breeder tank has fake plants in it as the cichlids will eat live plants and in a 40g they serve to break up sight lines and reduce aggression. This tank was set up 2 weeks ago and is cycling with 1 fish in there. Programming takes some time but once you figure it out the light is awesome on its 24/7 setting that starts with a yellow sunrise migrating to full day sunshine to a yellow sunset to blue moonlight to off. All fully programmable for color, time and brightness.Well worth the extra $. If you want to grow live plants I can’t even imagine how well they would do under a light that can deliver so much power if you turn it up. I have to keep it lower with fake plants to avoid an algae bloom. With a tank packed full of live plants you’ll grow a jungle in no time. ## Frequently Bought Together - SEAOURA LED Aquarium Light, 24/7 Custom Timer, Power-Off Memory,7-Row LED 12-18in Full Spectrum Fish Tank Light, 8 Colors, 20 Brightness, Day&Night Cycle, Adjustable Mount for Freshwater Plant Growth - Fluval 12694 Plant and Shrimp Stratum for Freshwater Fish Tanks, 8.8 lbs. – Aquarium Substrate for Strong Plant Growth, Supports Neutral to Slightly Acidic pH - PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic --- ## 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.com.ar/products/687659229-full-spectrum-aquarium-light-with-24-7-timer-for-12](https://www.desertcart.com.ar/products/687659229-full-spectrum-aquarium-light-with-24-7-timer-for-12) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-16*
