## Questions & Answers

**Q: Will one of these 18W bulbs work in a Coleman lantern that has been using a 13W bulb (hopefully, only draining batteries more quickly)?**
A: Doubt it. The base has plastic tabs that key it for different wattages, your light should have slots aligned to only take 13w (and possibly lower) bulbs. I think that the picture for this product is wrong, my 13w bulbs have the keys at 12 and 6 o'clock , and 18w has keys at 5 and 11.

**Q: Can this replace a cooper r10 13w/4p?**
A: If the base is 4 Pin G24q-1, then it will replace without a issue

**Q: Is this for G24q-2 base or G24q-1? It says g24q-2 in the description, but the picture looks like a g24q-1.**
A: G24q-2 as all 18watts are manufactured with the plastic piece sticking out on the bottom slightkh moved over from the center.

**Q: Is this truly rated for outdoor use? The Amazon listing says it is, but the actual packaging makes no mention of outdoor use. And the website is dead.**
A: I bought for indoor use so I can’t help you
