[PSUBS-MAILIST] LEDs

[Alan James via Personal_Submersibles]

Had 15 LED samples arrive today (see pic)They are all 80W & $6- each. The smaller round LEDs are bridgelux& latest 2016 FLIP CHIP technology. http://info.taiwantrade.com/EP/resources/member/275112/productcatalog/cd798993-dc6c-4548-810b-e7000d9ae1c4_INTRODUCTION.pdfThey are just over 1" x 1" & are the first I will make a housing for. I like the smaller size,as the glass lenses are expensive & the smaller the diameterthe deeper the light will go for a given thickness.I am impressed with the company I bought them from, Tongyifang Optioelectronics
http://www.tyf-led.com/products_list/pmcId=58.htmlEvery LED has my name printed on the back of it & I was gettingfollow up emails to check they had arrived.The other items in the photo are the buck / boost constant current led drivers.I have destroyed 2 of these already. I have a 48V battery bank with a pre-chargeresistor to stop current inrush to the capacitors. I am pretty sure I destroyedthem when I didn't use the pre-charge resistor.Alan
