Need to know a little more info. In our MH light fixtures, there are 4 different types of 12v light bulbs.
Pull a bulb from a different socket and look for a number such as 1041, 1042, 1076, 912, 921 etc. Bayonet base, wedge base. A lot of the e-bay sites use coding such as BA15d etc.
And then there is the colour, warm white 3500K, Daylight 5000K etc and the lumen output.
Lots of choices after you find the correct base. Yes, Hong Kong, China suppliers are a LOT cheaper. Just bought ours for about $2.00 a piece as compared to about $30.00 a bulb here. Took about three weeks to get ours.
