Hi,

I'm hoping that this is some sort of well known unit that is immune to googling under the name they're selling it under here, or something :D

Anyone ever used one of these ?

They are being sold as "CT-xxx High Power LED" here in Australia. 40w multichip with violet and blue emitters surrounding it.

Superficially this bears some resemblance to the Evil Cluster style lights people started putting together a year ago. Which would be great if they're using actual decent quality stuff like the same high CRI 4000k Bridgelux multichip the DIYers went with. But I can't seem to find any information other than what's at the OLFS's link here -

http://www.guppysaquariumproducts.com.au/lights-led/ct-high-power-led/ct-85w-marine-led/prod_3572.html

which simply says it's a 40w multichip ... so ... not very helpful.

Anyone own one? Of more interest - has anyone ever done a tear-down and seen what / whose LEDs exactly are being used in these units?

I'm just going to give this one bump before it sinks if that's not too horribly rude.

Scroll down the page and follow the 2nd link of user reviews and you'll find more information on these. I won't directly link because it's to another forum . If only they were using a neutral white for the main array, these would be worth looking into.

Yeah, most of the non-business registration stuff is repeated at the OLFS's link. Basically the one extensive testimonial on them is something they linked themselves in their PR bumpf, and it reads just a little too enthusiastic to be entirely trusted. I was wondering if there was anyone else who can vouch for them or can say what the emitters are.
