  5. connect cap with wires
  6. connect batterY

Step 5: LAST STEP

  • NOW YOUR LIGHT IS REDY
wow this is nice
<p>I would recommend soldering the wire connections and the LEDs. Looking at the LED's, it would be 10W LEDs. These would run down those 9V batteries in no time. Making them not suitable at all for emergency uses. Use more suitable LEDs because those 10W LEDs create a lot of heat. Gluing hot LEDs on cardboard is counter intuitive. The back side of those LEDs are supposed to be sticked on heatsinks to dissipate heat. Cardboard are insulators which means the LEDs will burn because of overheating.</p>
<p>You will definitely need a heat sink for those lights unless you want them to fail. Those led's generate a lot of heat. You'll need to attach them to some sort of metal plate with some thermal grease, or they will be dead in less than an hour.</p>
How many lumen? <br>
<p>lumen means??</p>
<p>Lumen means the amount of light that is given off from the LED.</p><p>You need a special meter to measure that</p>
it seems to be 12V 10W 900lm chip.. it cost about 0,75 USD each on alliexpress.
<p>What the sellers write pretty much doesn't mean anything, They just copy it from other people that put a random number.</p><p>But these LED's are actuslly pretty bright!</p>
It's a very nice project, just a commentary, it's fine to power the leds with 9v , buy the conventional 9v batteries don't provide much power, so yes , the led will light up, but it will last just 10 minutes or so before the battery starts running out. using old cellphone batteries might be an option
<p>its emergency light </p>
Dont left it on for too long ;). Wil melt in to your case ;)
Thanks for advising me !<br> i know my box will melt b'coz i used white cardboard <br>:)
<p>Nice project!</p>
