(1) The power size:
The power size of washing wall lamp has decided projection distance，in general has 18W,24W,36W,48W parameters. But power is not fixed。The power can changed According with customer claim，high power LED washing wall composed of the single row led， the LED line cast lamp composed of multi row led。
In addition，because the heat dispel problem， adopt single 1W to make washing wall lamp with 1 meters not more than 36W! otherwise，will be appear light attenuation when heat dispel situation is not good。

(2)voltage:
Can be divided into DC and AC，the in general built-in power external line AC220V(Japan AC110V)，external module as low voltage DC24V，DC12V，DC27V etc..
according with the demand 、different product factory and voltage。

(3)IP protection grade:
IP65   6 represents: completely prevent the dust entering
5 represents: not any harm with water washing。

(4) colors specification: divided into colorful, full color, monochrome

(5) the color temperature: about 2200K (amber) 3000K(warm
white)4000K(incandescent)6000K(white)7000K(cool white)

(6) emitting angle:
high power LED wall washing lamp(narrow angle) of the most distant valid projection distance is 5-10 meters。Lighting emitting angle is narrow so project distance more far!
