Help with Photoboost strip heatsinks in UK
Posted: Thu Jun 13, 2019 5:58 pm
Hi guys I'm trying to price everything up to see if its worth the trouble/costs of importing the Photoboost strips.
I'm trying to find heatsinks similair tothe suggested ones from PLC which are these:
https://www.heatsinkusa.com/1-000-wide- ... -heatsink/
Closest I've found that are avalible are these, that are basically the exact same profile but with 4 fins instead of 6.
http://www.mercateo.co.uk/p/5070-RAD(2d ... Quantity=1&.
Greengene on the youtube refference build video, says something to the effect of the recommended heatsinks do 14 degrees a watt, but anything between 14 and 10c per watt thermal resistance would be fine.
I know next to nothing about the math involved here. I've watched the growmaus vid on choosing a heatsink but most of that applys to cobs in what hes saying.
Are there any smart people out there that can help me?
At the minute my alternatives are possibly using u channel but I wouldnt know what size to use, so another math question for smart people lies within that.
My other alternative is to do a f strip build which would be a loooot cheaper and easier as I could use u channel and the strips are a lot cheaper as well, especially not having to pay vat(20% tax) plus a bit of customs charges. I'd realy like that 2.7/umol/ju effeciency though haha. Maybe I just do f strips and upgrade at a later date.
Thanks in advance.
