Track Light - 24v AC to 12V DC Cob Light 5-6W
Description
I Could Not Find Replacement Fixtures For A 24V Ac Track Light System. The Solution Was Easy; Replace Failed Track Lights With Led Cob Lights By Designing My Own Track Light Fixture And Printing It Out In Petg. To Convert Ac To Dc I Used A Bridge Rectifier Chip Which I Attached To A Buck Converter. I Salvaged The Contacts From The Original Track Light Fixture So I Could Plug My Replacement Into The Existing Track. The Old Halogen Bulbs Used 40 Watts Each And Generated So Much Heat They Melted The Ptfe Wires In The Fixture Leading To Shorts, The Track Had Some Singe Marks. I Rewired Some Of The Fixtures And Set My Buck Converter To 11.5V, The Bulbs Use About .25 Amps At 24V And .5+/- Amps At 11.5V.. I Tested The Led Cobs For Heat, They Only Got To 55 Degrees C. I Purchased Heat Sinks Which I Decided Not To Use. These Led Lights Are Generating Lots Of Light, They Are Operating At A Fraction Of The Wattage And With A Fraction Of Waste Heat. Better Yet I Did Not Have To Spend $1000 To Replace The 24V Track. Installed These Fixtures Work And Look Great. Cost Per Light Fixture Was Under $5...
