I inquired a little while ago about this option, the prices advertised are NOT real. I inquired on the vero 29 at 40$,
this is the real price breakdown
Bridgelux Vero29 Gen7/3000K/80Ra/38V is available in stock.
The price as below:
Bridgelux Vero29 Gen7 3000K cob: 21.5usd/pcs;
Glass lens KB-HB78-90: 3.0usd/pcs;
Heatsink Φ135*H70mm(for 55-65W): 11.5usd/pcs;
HBG-60-1400: 18.5usd/pcs;
Pothook + Plug + waterproof connector + Screws: 4.0usd/set;
In addition, you need to buy thermal paste, molex cable for vero29. ( these are not available for us )
complete kit comes to 58.50$ each so not crazy far off the advertised price but Shipping is killer, I asked about buying 4 of them and shipping to canada was 88 USD, thats almost half the order itself, plus duties etc. in the end with shipping for what your getting at 50w each, they are not that great a deal.
