http://www.advancedaquarist.com/2010/2/aafeature2#h2 Thought bros might like a read of this article by Sanjay Joshi. I never seem PFO I5.

This guy has done the comparison with some LEDs. epro (AquaLUMEN ) 19 Solaris I4 113 Giesemann 250WMH 80 Other LED 1 44 Other LED 2 201 http://www.reefcentral.com:80/forums/showt...9666&page=5

Assuming 1W@350mA is 100lm at 1ft distance, at 2ft, it will only be 25lms. The total brightness of 1W@350mA is 100lm, you never get 100lm at 1 ft. You have to add a lens with less than 5 angle.

you are right if you don't use lens with the LED. but normally I used to have lens with my DIY. Let's say the 3W without lens and 1W with 50' lens @ 2ft you can see the 1W is brighter than 3W for sure. What i am trying to say is unworthy to pay more menoy for the 3W LED.

I have a lot of experience on the LED DIY.I have been searching the new LED technology from internet. It tells me no worth to pay more money on the 3W LED. And the same 1W does't provide the same Lumens & PAR. Some 1W LED over 130lm, some less than 65lm.

1W & 3W are same, so you don't need to pay more money for 3W, just drive 1W with 1000mA than it is 3W. http://ledsupply.com/05027-pwc4-180.php http://ledsupply.com/docs/tffc-k2.pdf

The Comparison is done by Paddy from Perth WA http://www.masa.asn.au/phpBB2/viewtopic.ph...c&start=270

As I know MaxSpect using 3W so it has to be cheaper. The LED 1W & 3W are the same thing, the input with 350mA is 1W, and input 1,000mA is 3W. 1W x 3 is much brighter than 3Wx 1, even they have the same power consumption, and 3W provide 3 times of heat of 1W, the lifetime 2 tims shorter than 1W. I don't believe A101 just for a shallow, if it is exactly same as KR92. Here is the Comparison MH400W vs 24" KR92. http://public.sheet.zoho.com/public/paddyk...ting-comparison

more LED coming....... http://www.reefbuilders.com/2009/12/09/aca...-ecolamps-kr92/

I don't we can buy it in Singapore, i saw they have online shop www.eco-sell.com, you can check the price on it.

I saw some one posted the link, so I think it is ok to post www.eco-sell.com

I don't think i can post other forum's link in this forum. Will be blocked if i do that.

The one who has done the test, he just bought LED light and made the comparison, he was using T5HO, if the clams doesn't opening well, it because during the testing the light on and off, i think.
