Question: what resistor should i use if i run them to 12volts?
Document: Perfect! Purchased these lights to use for night disc golf and they work great and last seemingly forever (we end up losing them before they ever run out lol). If you're interested in doing the same here's a recipe:Ingredients:1. Disc Golf Disc2. Clear Packing Tape3. 2, 5mm LEDs4. 1 CR2032 BatterySandwich the battery between 2 LEDs (remember, short to short/long to long). Wrap tightly with clear packing tape. Flat-tape to underside of your disc.
Lovely quality as seen in the picture. I will be using a CR2032 to power these as they work well without a resistor for over 10 hours
These LEDs are nice and bright. They also come at an affordable price. I cant wait to use them on my next project.
Product works great , i use them to replace the ugly blue leds in my pc fans very nice n brite
LEDs are bright and work well I use these on my rc truck for head lights and they work very well shipping was fast too
I bought these to use as headlights for my RC truck. Super bright, perfect for my project. I only needed 2. These are the same price for 50 as Radio Shucks has for 2.
These lights are fantastic. Bright and easy to use. There were no bad lights in the pack that I could identify!Very very bright - one or two is enough to blind someone for a minute! Don't shine at a person's face.
These LEDs are nice and bright. They also come at an affordable price. I use this for nightlight projects trying out different batteries from triple A to lead acid,car batteries and old cell phones.
The shipping was slow (took about a month), but understandable since it's coming all the way from China. However not what I was looking for for my LED lamp. My fault on this part. Should have done some more research.To all buyers: the light is actually pretty dim if you want to use this as a lighting option. This should only be used as an indicator light in labs.
I purchased the items for my Chinese lanterns. I was hoping for some light for the wedding and it was recommended that these will work. Well, it didn't unless you buy individual small batteries and use maybe tape to type the battery and the light to it. Overall - it didn't work for what I needed ( I wish it did as it was bright and would have loved to be able to use them).
Answer: yes
