Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
At FESPA I saw a LED that is sold by Saati USA, 300W and costs $500.It will work like a spot light.They say exposure for a pure photopolymer emulsion will be about 45 set at a lamp distance of 36", at this distance I can expose two 23X31" screens.I am ordering this unit.
What emulsion were you testing?I have a problem, my unit works well but I have flouresent tubes and have to improve on this.All the alternatives are really expensive, I was looking into putting rows of LEDS into my unit but this lamp looks like a great option.Greg from Saati said the 300W unit can expose Textel PHU in under 1 min at a distance of 36".This works well for me and at $500 it's a reasonably priced solution.My son is coming back to Israel on the 11th June and can bring one with him so I have about a week to decide.

You have at least one auto (with a DGT printer in one station) and you want a $500.00 exp unit? Seems like for the cost, it would be under purchasing for your shop. I don't know. Could be very wrong.

One is the 300W prototype and the other is the 450W water cooled single point light source. Give me few weeks to get some results. We burned few (3) screens with the 300W unit, but that was just preliminary testing. We were at 2 min for the 110 mesh to get no slime on the back.pierre

It didn't live up to the claims they had made to me about exposure times. On the SP-1400 it was worse than our 1k MH unit I've had since we opened. That was a annoying sticking point from them, they said I'd be better off switching to their newer hybrid H-something. Then we thought maybe the unit I got was damaged..... All in all I ended up returning it. It performed below our 1k Workhorse we have had for 10 years. Important to note though, ALL the use and screens we did with it were for DC, WB or HSA inks. Didn't try it on anything for plastisol.

I would be suspect that as every manufacture is producing LED units that cost thousands that any unit that cost $500 bucks can't be much to write home about. Comes off to me like a late night TV advert... but wait there is more....act now and we will throw in a brand new 12 color auto with your purchase.....just pay processing, shipping and handling.

We are not comparing apples to apples here. This is just the core. This is not an exposure unit, just the light source.http://www.theshirtboard.com/index.php?action=dlattach;topic=13347.0;attach=13534
