The DKM and DLR lamps operate at 21.5 volts and 250 watts, they use the G17Q base which is used in the Bell & Howell 16mm projectors from the 641 onwards. However, whilst using the same base they are much shorter in height than the B & H A1/207 lamps (1000w).

The DKM and DKR lamps are used in the Graflex 16 projector, they appear to be same except that the DKM has a colour temperature of 3200 degrees K, and the DKR has 3300 degrees K.

Do any Forum users of this projector have any views on the differences between the two bulbs?

A further question. Do these two bulbs have an A1 number which is used in the UK?

Hi Maurice,I have a few of both bulbs.The only difference I see is that the DKM box says 25 hours and the DLR box says avg 10 hours.I see no other differences or box codes except the DKM lamp sells for a few dollars more.

Richard
Thank you for the reply.
As I said, the only apparent difference between the lamps is their colour temperature, but as it's so minimal, it seems very strange that two lamps are manufactured which are so close in their specification.
