Sometimes if you tell the sender to invoice under 1k then you don't have to pay tax when they send it out to you. That's what happened to my boss when he ordered a 3.5k camera and they invoiced him like 900 for it when they sent the parcel to him.

Jut ask Milard about splitting the shipping. I split my order into 2 (so I had 2 lots of freight) and he gave me a discount code so I could reduce 1 order - worked out to within a few $$$ of 1 shipment.

You can do that, but what do you think your insurance company will say when you make a claim after loosing your new camera?? Here sir is your $900.

So, you save $350 in GST, and loose $2,600 on your insurance claim.

The 5.2 looks good - I didn't like the wiring provided on the 5.1 so that is a big improvement.

The older version 5.1 100w is the only one that has a red led. Wouldn't this be the "fuller spectrum option", not the newer,more expensive 5.2?Sorry i have no idea when it comes to lighting. Its my reefing weakness. lol
Layout of reef version:
Channel 1 - Neutral White (base white spectrum) (36V @ 700mA)

Channel 2 - Royal Blue (base blue spectrum) (36V @ 700mA)

Channel 3 - Hyper Violet (enhanced growth) (38V @ 700mA)

Channel 4 - Deep Red / Turquoise (enhanced color spectrum) (32V @ 700mA)

Channel 5 - True Violet / Cool Blue (enhanced growth and color spectrum) (38V @ 700mA)

@OSCAR85

I haven't had a real good look at the specifications of the newer 5.2, but based on:

Layout:
Channel 1 - 3 Hyper Violet and 2 CREE XT-E Royal Blue (Actinic channel) (18v @ 700mA)
Channel 2 - Royal Blue (base blue spectrum) (16.5V @ 1500mA)
Channel 3 - 3 XT-E Netural White and 2 XT-E Warm White (base white color) (16.5V @ 1500mA)
Channel 4 - Turquoise / CREE XPE2 Blue (enhanced color spectrum) (17.2V @ 700mA)
Channel 5 - - 3 Hyper Violet and 2 CREE XT-E Royal Blue (Actinic channel) (18v @ 700mA)
they have included a few Warm White LED's which have a lot of red in their spectrum - this is the effective substitute for the deep red LED's.

I can assure you they are 3 watt leds, however not sure that means anything since the driver you use determines the power of the led. we make the Lumia's for Milad here in Melbourne so know exactly the leds that are used
