I've already read the how-to and looked at the Youtube. I have an older light and the rep said that some of them had some problem that made them harder to insert the new bulb. I seem to have one of those. I've replaced OttLite bulbs before with no problem but this one will not snap in. If I can't figure it out, I'll probably just throw in the towel and get a different light. Preferably one with some help that doesn't close up shop about the time I get off work.
