Do the slits on the side allow light in? I am trying to block out blue light from all sources (even regular light bulbs).

I have no idea. I used it for one task only and they are now packed away ready for my move out of state; so I have no idea where they are. Sorry!

no, they don't. They're angled so it doesn't get in. don't know why they are there.

Nope. While not stylish in the least, these are GREAT at blocking out the blue light. Perhaps if you did a handstand, a bit of light might leak in from under your eyes. But apart from that these are great. I wear them on my drive home from night shift even if I look ridiculous. :)

None that I am aware of at present. I installed my Full Spectrum Light Bulbs (ALZO 45W CFL) in light sockets without a globe or shade (not my original plan). Used in this fashion they throw a lot of light as long as you aren't too concerned about appearances. One is mounted horizontally and another vertically. Both have been in service since the beginning of this year without any problem.

I am not sure what you are referencing, but it does not block out blue light. Nor does it add a blue hue. If you could clarify your question I would be happy to answer.

Thank you for responding. After your answer to me, I looked more carefully at the insert, and found the slits.too. I was all prepared to send it back and be miserable thinking about another sleepless day. Thank you si very much for saving me.

not really. i guess with a strong light it might allow some light through. however, under normal conditions no light gets through

No, I don't think so... in fact, the lamp these fit for me had a completely enclosed bulb area... in other words, nothing was left open. Sorry.

yes. there is a switch on the unit. i'm curious, tho, why would you want to limit the light?

No, but you can turn them on 2 by 2 so there some minimal control of amount of light. You can also play a little with the extra filters.

It will block UV but I don't know about blue light. You cut it to fit screen.

No glass lens, bulb socket points to the side, and nothing 3" long will fit in here. I used LEDs that are less than 1" long, I believe they are described in my review of the light fixtures.

I don't think it would block all light from a day window but I wouldn't call it transparent at all. These are very nice tablecloths and they have a quality look and feel. I have a white one used in a wedding meal. Looked great.

I have the black, gray and green curtain. It's thin enough to allow light in, but still able to provide plenty of privacy. Hope this helps.

They block enough not to see through but if there's a full moon light gets through. They aren't black out so if the spot light is close I'd probably say no.

Yes, these will block blue light from TV as well as other electronics. Bear in mind that it will slightly alter your viewing experience, for when blue is filtered out, a lot of colors change.

Yes there is circuitry on the back side but I put them in the smallest of fixtures to replace my halogen bulbs. They are a pain to put in as you have to slide the prongs in at an angle. Worth the effort and the cost though. They seriously cut my energy budget.

Hi Eric! The white will show through a bit of light, though the others keep the majority of the light hidden. A bit will peek through, though it will be a lot less than without the covers. As some customers have mentioned here, it's all a matter of preference and may depend on how much light you need. Apologies if that is a bit vague. If there's anything else, just let me know. I can be contacted directly via this link:
