Schoolboy question here, but I've just receieved my Alpkit Gamma and from the picture I thought it had one main bulb and three smaller ones above it. Now I've got it, the three smaller ones above appear not to be bulbs but I'm not sure what they are or what their purpose would be??
I'm not overly fussed as it's a great piece of kit at the price, just wonder if I'm missing something.
