鴨記,有一間有開左一粒做試辦的$99 (其他店好.P.K,唔理人,問都唔想講{可能佢唔識} )

限流
LED發光是以電流強度,不是電壓! 當電流超過LED Imax,LED便會燒毀 *** LED唔知飽***

有錯誤請指導 :helpless:

發現甲鳥言己有得賣 CREE MC-E LED HK$168,

http://www.cree.com/cn/products/xlamp_mce.asp
它是 3W LED x4 在同一粒燈裡,
外觀跟一般 3W LED 一樣,
網頁話熱量同一般 3W LED 相約,
但光通量可以高達 700 流明以上,
包裝有 4led 串聯 / 4led 獨立,
用 raytang 的安裝方式可以, 只是供電不一樣,
因為它基本是 3W 結構, 可以用"恆流源驅動"供電.

大家點睇 8-)

Thx thx.......very important to learn this...

I've found this. Their office in MK and the lady is very helpful
http://www.energy-bright.com/product.htm

Total 5W (3 LED), US chip, the brightest LED they had....
Very reasoble price (not conveniecne to disclose here)

It's 12V and can use the traditional spot light base....good outlook and easy to install...
Will buy it for DIY soon as quite busy right now.....

WONDERFUL ^_^

Your recommended model is very powerful .....700 流明....must have very good water shadow!
The one I found is around 150-200 流明 only...

$168 not bad but need to think about the case design...

Consider to buy!!

不如用 P7 啦~~900流明仲勁,不過要2.8A,有D難度~~
