Native marine aquaria are pretty scarce. Little information exists on how to be successful in maintaining healthy coldwater marine systems in domestic aquaria.

Hopefully this record of my failures, triumphs and ideas will assist others interested in keeping some of our fascinating, beautiful and often little known sea denizens in aquariums.

50W LED floodlight

In my seemingly endless search for practical and cost effective solutions to lighgting the aquarium I have tried many different things. My latest experiment will be using a 50W LED floodlight purchased through Amazon for £69.99 (free P&P).

According to the manufacturers description this light is equivalet to 500W halogen, at 'Cool White' a temperature of 6000 - 6500K is good for aquarium viewing and at over 4500 lumens it packs some punch. With an exterior grade housing it will be safe to hang over the tank - looks pretty good so far.
Whilst an (almost?) identical unit can be purchased for around £35 direct from Hong King on EBay, postage at £18 makes this significantly less attaractive. Buying though Amazon does give a certain peace of mind in the event of the unit not living up to expectation or breaking down.

If this lamp passes muster I'll be buying either 3 or 5 more to supplement my Light Panel.

10th June update.....

Unfortunately the lamp was 'warm'. Around the 3000K temperature which is utterly useless to me. I returned it over 2 weeks ago and have yet to either receive a replacement or an indication if they do actually sell a 'cool' lamp (6500K) as advertised or if they dont have a clue what colour temperature even is!
Getting a bit cheesed off!


  1. If you're looking for a way to shed the maximum amount of light on your yard, driveway or deck, outdoor flood lights just might be the answer. These lights typically are used for security reasons and also to illuminate a yard, deck, or driveway. Their primary purpose is to flood (or blanket) an an area with brightness. They also come in a wide range of styles, sizes and light intensity. Although these lights are most often associated with safety and security concerns, they can be also be used as part of a decorative landscape lighting design.

  2. WhatYouSea sells coral frags on the internet for people with saltwater aquariums. A coral frag is a small piece of live coral that a person can add to their tank,and grow out. The niche should be blogs related to saltwater aquariums, and coral propagation and sales. Let me know if you need more information.
