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!
