Cheap parts for projector, spherical reflector, condensor lens, flat cable/connectors

Good news!

Everyone remembers YWH from Guangzhou, THE guy who first posted results of an opened LCD monitor? We know he has access to a lot of cheap parts in China. Now, YWH is willing to provide spherical reflectors, condensors, and flex cable / connectors to the forum. He is negotiating with DIYlabs.org to see if he can provide bulk and DIYlabs.org can sell them. If Alan at DIYlabs takes his offer, everyone here from US will benefit from the low price.
 
I asked him to buy a HMI type lamp for me. I don't know if it is Xenon, but it looks awful alike.

It is very cheap. the problem is the ballast. it is 220V, and heavy. I need to buy a 110/220v transformer in order to use it.

The lamp will arrive next month. If I find time, I will start to mess with it.

That lamp looks IDENTICAL to the lamp in my ELMO 305. Mine is a 575w MH. $82.

It was not the picture of the real lamp I will get. It should look like the one YWH posted earlier ( i tried to find it yesterday ) :

An externally hosted image should be here but it was not working when we last tested it.


As for flex cables, I believe there are more than one size. We might be able to pick up our 'favorate' LCD monitors, and find suitable ones for them.

Now, just hope DIYlabs.org would consider YWH's proposal.

and did YHW mention anything about selling HQI bulbs/supplies?


No. But I think it could be done, if bulbs can survive the transportation. Again, I don't know if you can find a ballast for it in US. I don't have detailed information of the bulb. Although you can find a lot of stuff cheap in China, but the information is almost always imcomplete and inprecise.
 
Alan at DIYlabs is interested in the HMI lamps (pictured above), but the problem is the ballast only works with 220V, and I couldn't find matched ballast in US.

Anyone knows what the structure of a ballast? I mean, does it just like a special transfromer? if so, the simple way maybe just find a transformer which can produce the same working voltage maybe a way around this ballast issue.

EDIT: just found some information on this site:

anyone can translate it in to plain english? :scratch:
