Can a brighter bulb/led be added to the Pentax spotmeter IV.

[eli griggs]

Like many here, I use the Pentax IV spotmeter and, like you, I am frustrated by the tiny dim light that only illuminates the lower end of the scale.
If it was a bit brighter and would light the first half of the scale, that would be great, but it's a couple or three EVs from showing this.

Is it possible to replace the OE light source for a brighter bulb into the meter, has anyone tried and is the meter hermetically sealed?

If anyone has something to say about this topic, I am sure as heck listening.

Talk to George at Quality Light Metric in LA. https://www.yelp.com/biz/quality-light-metric-hollywood He got the little light in my Pentax spotmeter working, and calibrated it. Turnaround time was, IRRC, about two weeks, cost about $100..

Or else, check with Richard Ritter, who also does repair and calibrations on these.

Yes, he is the go to man!

I find that it only ‘needs’ to illuminate the first few numbers. When readings are above that there’s usually enough light to see the scale. Suppose if you are in a nightclub the story is different.
