They are only 100 lumens. Not very bright. You should look for a minimum of 200 lumens and more is even better. If you are looking for a LED to read by you will need to be up in the 400 to 500 lumen range. Don't be confused by the number of LEDs on the lamp because some times fewer LEDs produce a brighter light. If you plan to replace halogens with LEDs make sure you have the right base. The ones you show are a "wedge" base. I would imagine your rig also has lamps with "bayonet" base that is a twist and lock. Two styles for that also, horizontally opposed pins and horizontally offset opposed pins.
The short message is look for how many lumens it has. Some rate it by watts and I am not into that comparison. I'm sure there is a chart to cross reference them also.
Last, there are different colors. All white lamps are not necessarily white. There is cool white and warm light and other colors in between. Without a little research I can't tell you the difference in color but believe me there IS a difference. Some may have a slight blue tint which may be objectionable or maybe not.
Shop around on Ebay and be patient. You will find the same LEDs for vastly different prices. Check their feedback also. I like to have feedback to be north of 95 and check what kind of negative feedback they get.
