This is a brand new LED replacement lamp house for the Omega D2, D3, D5 and D6 condenser enlargers. It replaces only the existing lamp house so you keep the condensers and the ability to use above-the-lens VC filters. The primary advantage is the total lack of infrared radiation, so the negative will not heat up, no matter how long the exposure. This prevents shifting and popping of the negative which can ruin focus. Also, since the light comes only from the center of the lens there is much less stray light than with a bulb which tends to reflect a lot of light off the black lamp housing. The end result is that prints made with this product are very, very sharp. Glass negative carriers are not needed for most negatives. The unit is a real pleasure to use. Build quality and uniformity of illumination, both spatially and temporally, are superb. Ilford VC filters work as expected with this unit. Exposure times are similar to those of a 150W bulb. Uses 110VAC, 9.5W North American standard power. Asking US$150.00 plus shipping however you want.
