So we are talking 6.1 metre length, useable light area 4.6m. I assume 1 metre on the walk way. so light area approx 4.6 x 1.35m hanging from approx 1.5m? Light Area 6.2 square metres, sound about right

With that kind of space to light up, you're almost going to have to utilize some kind of light mover imo. That's just sooo many cobs. Unless you got the coin, then by ALL means, fill it with COBs. :D

ROI for cobs is even faster when you're buying a new setup rather than replacing an existing light. Dropping 10 grand on a 20ft trailer setup that should pull a minimum of 5 elbows/cycle. Thing should pay for itself on round one.

I'm sure Mark will look after me. Ha ha.
I'll see if I can get some time later to draw a plan up and see what Yas reckon.

that would be cool, if you can out up an image I can give you recommendations, will clarify what area's to light, no point spending on light that wont deliver you cost effective yields

Just curious about my 10 cob order #20096? I'm excited to get started building. Can you recommend a potentiometer to dim them? They'll be used in one fixture for a 4×5 space. Will that even be necessary? Thanks!

Dimming is useful if you want to work under the lights and not be blinded ;) I don't buy the natural sunrise/sunset mumbo jumbo that KIND LED spouts.

I have a specific Bourns pot model (oops "potentiometer" here) that I like, IP67 sealed, conductive plastic element, $3 but Cutter will only email you the PS spec sheet so its a bit of a mystery what they use, usually 5-10K.

I use the cutter dimmer and it works just fine for me

Thanks Mark!

A good quality pot would be the Bourns 3360 series, 3360Y-1-104LF (50k, $3 at Mouser) or 3360Y-1-503LF (100k, $3.75 at Mouser) all IP67 with a 0.25W conductive plastic element, these cable mount nicely with soldered wire (to PC pins) and inner melt heat shrink or panel mount and you don't need a knob, you can turn the little 0.1" x 0.25" shaft with your fingers.

The fancier choice for this could be the Vishay P16SNP104MAB15 (100k, $13.42 at Mouser) or P16SNP473MAB15 (47k, $12.40 at Mouser) both IP67 with a 1W cermet element rated to 316 volts with solder lugs, it comes with a built in knob and is good for cable mounting as above, or panel mounted with included hardware.
