Lighting Homemade Chinese 2x 50w Cobs for £27/$35

[MickJ]

Ok so having made one light I thought I would try the double [emoji16] I went a bit fancier on the heatsink at £7 each ($10). 50 watt Foxanon 50 w 4000k cobs at £1.60 each and a 100 watt Chinese driver £6 wired up in parallel. Total cost about £27 with wire, couplers and thermal paste or $35 depending on your side of the pond. My soldering is getting good too [emoji39] Hanging them tomorrow. Heatsinks and cobs from Alibaba -took 1 week for heatsink and 2 weeks for cob delivery. Driver was from eBay and took a week to arrive. I could have used citizen cobs for an extra £16/$20 but wanted super cheap to see what they will do. I bought spares in case they don't last. It will take me 10 minutes to change them out including soldering. I could have gone fancier on the hanging wire but the plants don't care.

I just made them tonight so they are going in the room tomorrow. Took me an hour. So not a big deal and not technical. I have a single one I made for my nursery and the girls are loving it but only been a few days so time and bud size will tell.

Good DIY job. Love to see used items get re-routed for another purpose. The Green Goddess is smiling.

@Dudeski can this be moved to DIY. I couldn't find the category for love or money.

Here's the parts, I bought the wire and connectors locally. I used the lever ones so I could change cobs or wire length easily. I also bought M3 bolts for the cobs from ebay. -£1.50 for 30 from eBay. Thermal paste I had from pc days but can buy for a £1.
