Available in widths of 60cm and 90cm, the Flat One+ Pendant adds a stylish, expertly engineered hanging light to freshwater/marine aquariums. This revolutionary smart light allows you to digitally manage the lighting environment within your aquarium.

LED Technology:

ONF lights feature the exclusive wide-area colour rendering technology of ONF colourful LED. This highly engineered lighting solution provides the essential wavelengths of light required by aquatic plants, this technology also compliments the spectrum of other colour bands, leading to a vivid appearance of aquarium fish and plants.

In addition to the colourful LED technology, there is a choice between two further LED options:

  • YW (Warm & White). The Flat One+ (YW) model is a combination of ONF exclusive colourful LED technology mixed with warm white LED’s. This provides freshwater aquariums with a sunrise and sunset feature, which replicates the atmosphere fish and plants will experience in their natural habitat.
  • BW (Blue & White). The Flat One+ (BW) model provides a more complete spectrum by combining ONF colourful LED technology with blue LED’s. This makes this light suitable for both Freshwater and Marine aquariums.

ONF Link Phone Application:

The Flat One+ can be controlled from a smartphone via the ONF Link phone application (available from the App Store, and Google Play). This application gives users the ability to set multiple timed schedules at different brightness levels and various colour temperatures.

Light Hanging Kit:

Left and right hanging kits are sold seperately.

We have been working closely with NT labs for many years now. We stock their Pond range and test kits, we strongly believe they are the best liquid test kits on the market, we use them in-store and have sold many over the years. Last year we have began stocking more of their fantastic ranges including their Pro-f food range and Aquarium range of water treatments.

“I Just wanted to say thank you for the help with bacterial issues I had in my pond. I can happily say that the mouth rot of one fish and the fin rot of two others has cleared up to near perfection now. I have been really impressed with the service from your technical team. I have already recommended online that people ask NT Labs about their products and recommended usage.”

Your Probiotic food is absolutely brilliant! I bought twenty one 1 year old Japanese Koi via a fish farm in Ogata, Japan about 3 years ago. I’ve been feeding them on Probiotic and Probiotic Growth in the summer months. Some of are now 2ft in length and of superior quality. It’s not cheap, but you get what you pay for.

I have used many products for the eradication of aiptasia over the last 15 years. Often with poor results. After purchasing the Anti-Aiptasia, I was astonished with the results! Absolutely fantastic and not like the competitors which normally contains some form of hydroxide. I would highly recommend NT Labs Anti-Aiptasia. This is arguably the best in the market!

We use Blanketweed Balance, and find it highly successful in the battle against Blanketweed. We recommend it to all of our customers and feedback is very positive. It is now our best selling Blanketweed treatment. Another top quality product from NT Labs

I work at a pet store in Durban (South Africa) and have had the best results with my salt water aquariums that I have EVER seen. I have been in the industry for about 10 years now and seriously recommend the products supplied by NT Labs. All our customers that have used anti-aiptasia swear by this product and have said that it over rules every other product out there. Highly recommended.

"I called your offices for support and was put in touch with one of your Aquatic Biologists. He has been incredibly helpful... Without your help, my fish would be suffering and I might have had to stop keeping Koi. I cannot recommend your products, or staff, enough."
