I have a little insight to the 100 watt goboman projector. I purchased the 100 watt unit at MBLV. When I brought it up to my room I took a closer look at it. I found that there were 100 watt stickers placed over the 75 watt words printed on the box. After examining the unit there were no stickers on the unit itself displaying any information. The paperwork from the box said the unit was rated for 75w/100w/250w halogen lamp x 1 supplied. I'm now figuring that all they did was include a 100w bulb and up the price $20 but it's the same housing.
The next day I asked the goboman these questions (no other customers were present at the time). He got very piss off with me for even questioning him. I wanted to know what the difference in the units were and not just the bulb. He said and I quote "I don't know, take the unit a part and find out". He went on to tell me that the 75w unit had a sticker on the back of the housing, the 100w didn't. He also said that China shipped the 100w units in the 75w box so it was easier just to make up his own stickers. While being very pissed off because I asked for an explanation he did tell me I could return the unit. I of course said no, that I just wanted to know what the difference was. He wouldn't look at me, talk to me, then just ignored me.
I don't know how the unit works as I haven't tried it yet. I read that DJ Scottie used it and like the unit so I thought I'd take a chance. I'm sure the light works just fine but I can only conclude this: The 75w unit and the 100w unit are exactly the same. They are putting in a 100w bulb and charging an extra $20. Stickers have been placed over the original box and the specs sticker has been removed from the back of the 100w unit which is probably the 75w unit.
If anyone who purchased the 100w unit has anything different please let me know.
