Which one is your top line LED and how much would it cost ?

Our one and only flagship LED grow light is the Holographic series 1- http://www.grownorthern.com/holographic-series-1-led-grow-light.html it retails at £312.50 excluding VAT, £375.00 including VAT if your in the EU. The unit only currently accepts 220-240v AC mains input so it can't be used in most of the US and Canada with out a transformer at the moment.

Where can I get a transformer? And how much do they cost ? And what is the coverage area for the light? Thank u ~

And related to using a transformer in the U.S., what is the loss, if any, in terms of efficiency, added electrical use, etc. for the unit with vs. without using a US voltage adapter?

I found a US company and an EU company that sell the step up transformers but neither list the efficiency. The efficiency would depend on how close your load matches the size/output of your transformer. If the load matches closely for example you use this this transformer http://www.voltageconverters.com/itemdesc.asp?ic=VC100W for 1x 75w unit I imagine the efficiency would be quite high, 95%+ which would be 2-3 watts extra power consumed.

The light coverage area varies from application to application based on the intensity of light required. This can be altered by using different Holographic diffusers or different hanging heights and angles. For higher intensity applications like flowering higher plants I find the ideal coverage and intensity area of 1x HS1 to be 50-60cm.

I'm no electrician, so probably a reason for it, but if one is available in the area you're setting up would the 220V two phase line found in most US houses (usually for the clothes dryer and maybe one out in the garage) work? With the right plug adapter, of course.

I don't know the specifics of the US 220v two phase line but I remember there was a discussion about this in another thread.

Hey Corgy, 220 volts in the US is achieved by using 2 120 volt conductors where the frequency is 180 degrees out of phase with each other vs. Europe and a lot of other areas where a single conductor is rated at 230 volts.

If the above quote is correct the 220v line would not be applicable to use with the HS1.

Here is the Electrical input data.
