Blinding bright
When I first ordered this item, it was suppose to replace a 30W Halogen bulb.Since the halogen runs on 12V AC I put a rectifier in the circuit and basically had my 6V DC. Apparently the Adjuster circuit did not tag along so I literally burned this one up. I have noticed that instead of using the Voltage range of 6.5-7.5V it is better to use less (5V-6.5V).
I am surely surprised how bright these are.
Nice!
Had a coach light that was very expensive, lost 2 of the leds out of 3, thought I was going to have to replace entire fixture. Found these little gems online, they worked perfect! I have very little electronic background, but it was very easy to solder new leds to leads and reinstall. Each led as bright as a 25w Edison bulb, If I was to guess, very nice, buying more to have on hand.
