Re: Fluorex Lights

Well I'm not sure about the lumens, I haven't been able to find any claim by
LOA regarding lumens, only Watts, CRI and Color Temp. The only lumen claims
I found were on eBay from people selling the light at twice it's retail
price. On your last note, yes the lamp is considerably bigger than a normal
compact screw in (were you able to see the pics on the UniQuaria messages?).
I think if you were to "straighten" out the tubes you would be looking at a
similar surface area to a 55W CF. I doubt this is a "super lamp" emitting
120+ lumens per watt like some eBayers are suggesting but it does looks
quite bright to the naked eye.

Yeah, me too. I like empirical evidence and could care less about anecdotal
evidence. I don't like some of LOAs wild claims. I want to see those claims
backed up by scientific evidence. I have always wondered how they could get
away with those huge lumen per watt values. There are rules about lamp
labeling covered under the appliance rule and rules about how lamps are to
be tested. I suspect that small specialty companies must be exempt and maybe
LOA is one of them.

I find that many aquarium lighting products are sold to hobbyists under
false pretences. The marketing is generally designed to trick people into
thinking they are getting something they are not getting. It really bugs me.
So, I try and promote the idea of buying from companies that give real
useful information about their products.

That Fluorex lamp may not be so terrible either. I just can't tell from what
LOA says about it. Panasonic makes a similar lamp which is about a 60 lumen
per watt lamp. If the "tines" of LOAs lamp were longer it would likely be
more efficient than 60 lumen per watt. Anyhoo...even if it made it to70
lumens per watt would only be typical of any compact fluorescent lamp.
