Environmental friendliness vs price?

Found some writeups about Lenovo 2GB PC3-8500 DDR3-1066 Low-Halogen SODIMM Memory P/N: 55Y3707 in the Lenovo Website:

Now in terms of price, Lenovo Website sells the standard 2GB PC3-8500 1066Mhz DDR3 SODIMM Memory P/N 43R1988 for $74.95 while the 2GB PC3-8500 DDR3-1066 Low-Halogen SODIMM Memory P/N: 55Y3707 for 73.99 so there is no significant price difference.

Still need to know more info and comparison vs. standard NON low-halogen memory so I hope we can find more folks who got more info.

Is it better to pick one from the other so any one is fine?

All of that with the possible exception of the "Environmental Information" section applies to the regular memory as well.

So are you saying that both type are pretty same such as general specification, compatiblity, performance and price but the low-halogens are just more environmentally friendly with lower heat and power consumption which transalates to longer battery life?

No, with a greener manufacturing process.

LETS GO GREEN THEN AND PICK ECO-FRIENDLY PRODUCTS!...I HOPE HALOGEN-FREE LENOVO MEMORY WILL AVAILABLE SOON IF NOT OUT ALREADY

I did more research and found more about "Halogens" in the Hynix website:
http://www.hynix.com/gl/sm/green/green_ ... nuNo=6&m=6&

Risk of Halogen
Halogen Group Material
Halogen group materials are listed as Flourine(F), Chlorine (Cl), Brome (Br), Iodine (I) and usually used as flame retardants on packing material in semiconductor industry.

Harmfulness and Need to substitution
-Cause noxious material like dioxin, difuran when flame and provoke environmental hormone stacking in human body
- Also knwon well that F,Cl,Br destroy ozone layer when exposured in the air
- It is needed to substitute because it is expected to make regulation from EU and Japan
