i can get about 10 of them for about 30 bucks121 and 112 LPW respectively. 121 isn't bad. Depends on how much they cost and whether they're directional.
closest i could find look the same but these ones are like a hard caseing and plug in like a cfl buld other things i says they have a onboard chiphttp://au.dhgate.com/product/hot-cheap-x2high-power-5w-7w-9w-12w-cob-cree/191783659.html?utm_source=pla&utm_medium=GMC&utm_campaign=mtled8&utm_term=191783659&f=bm%7c191783659%7c117005-IndoorLighting%7cGMC%7cAdwords%7cpla%7cmtled8%7cAU%7c117005010-Downlights%7cc%7c%7c0LWF%7c&gclid=Cj0KEQjwi-moBRDL4Omf9d_LndMBEiQAQtFf85S2iZ5CVwqNpo2r5j_pOWQbc1oLMZ1p-TjHqEUg-t8aAgte8P8HAQGot a link?
