Decided the Led a few 3W 3000 ～ 3500K is colour temperature Of 130 ～ 140LM. .
Seeing parameter is pretty good.
- - norms: 3W high-power Bai Guang　
- -Colour temperature: 3000-3500K (the light that is golden color actually)
- -Luminous flux (brightness) : 130-140LM(lumen)
- -to voltage: 3.0-3.8V
- -Power: 3
W- -Angle: 120-140 is spent
- -Use electric current: IF=700MA

Angle according to a few here friend is mirrorred, the light dark golden color angles comfortable.

Studied by Increase with MBT day today afternoon,[link widoczny dla zalogowanych], consulted a friend that has experience,[link widoczny dla zalogowanych], make clear Hunan at long last.

Also be actually those who comparative is simple.

Come home ravel oneself night angles the lamp, do not tear open do not know, tear open frighten jump, this circuitry comes simply.

The plumbic acerbity batteries that is a 4V + lead + switch + archives on any account two resistor + the homebred Led 3W

Without circuit stabilized voltage constant current,[link widoczny dla zalogowanych], this lamp is in no wonder the meeting is darker and darker later.

Adding electrify block and Led lamp is series connection, the as batteries group voltage in using drops, Led carrying electricity also drop subsequently, so the lamp is to be in actually darker and darker. And resistor also is in loss n, can angle before actually 20 hours, the n about the same half is waste is in above resistor.

Prepare to change Led lamp so, add module drive power source on two groups constant current (switch archives on any account) when can making Led angles in night,[link widoczny dla zalogowanych], be in all the time be close to full power to work (it is course deducted safety factor)

Will order a few module again tomorrow, after arriving, when spending the New Year, can mix angle elder brother a few night such as Laomo bright red elder brother angle maniac was enjoyed one pail ha. .
