Anyone messed with the High Intensity 3W LED's?

WELL I dont have any testing to back this up - I can only go off the info I got from the supplier?

I have 6 tubes and each tube claims to put out "100 WATTS OF LIGHT" & "697 Lumens". My Tubes are three feeet long each. The thing is the intesnsity is verry sensative to the incomming voltage! Before I installed my power convertes (from 110 to 80V) the tubes were CRAZY bright - BUT they would burn out. Now I have the converters on there they are consistent and not burning out but less intense.

If I was to go strictly off the Manufacturers info I would say 600 watts output.

However my gutt tells me is probably more like 400 to 500 ish???? I may be WAY off????

About the shimmer - they less tottal # of bulbs you have the more of that shimmer affect you seem to get (the bulbs must be intense!). But when you start ussing thousands as I have in my current set up - you seem to loose the shimmer. The proof of this is look at your tank with just the MOON led's on at night. I have about 20 and you can see that the shimmer is noticible. However during the day when I got 1300+ LEDs going the shimmer is barley if at all noticible. I think you can see that shimmer affect from most any bulb EXCEPT a florecent.

Well, the simmering effect is the result from the bending of originally parallel light leaving dark spots (shadow) at the bottom. What you said about having alot of LEDs kill the shimmering is true. It works the same way as the emergency's operating light they have in hospital. They have many lights shining drom different angles so... no shadows. Fluorescent and compact fluorescent is too long and often has more than 1 bulb there for the light comes from different angles thus no shimmering. Same with your thoundsand of LEDs
Sorry for the long lecture i tend to blah on :D
But that's why I prefer few high intensity LEDs with spacing between them. I basically have a fluorescent as base lighting then LEDs as additional. So the tank wouldn't look like a opera stage with spot lights.
 
I understand - I was considering a "ROW" Of high output LEDs in addition to my LED tubes. I love that Shimmering affect and was thinking I might be able to create it with a few HO LEDs. It seems like what’s needed has bin Identified. Now all I need is to start purchasing parts and start assembling. My hesitation is the heat. I originally got rid on my H.I. Fluorescents because of the heat! I am concerned about how much heat the H.O. LEDs will produce as I have a fully enclosed wooden canopy. I guess I just need to Give it a try and see what Happens? I am nervous about it though.:uhoh:

Hey Arkangel77
Could you please post the site that you purchased the led tubes from, I would like to read about them. Thanks
 
Thanks for the info.
