Everbeam 395nm 10W UV LED Black Light - High Performance LED Bulbs, IP66 Waterproof – Ultraviolet Flood Lighting for Aquarium, Indoor or Outdoor Parties, Stage - Party Supplies, Halloween Decorations

I used the 365nm 50W to make a4 cyanotypes. I set it up on an old desk lamp arm about 20cm above the paper. Holding down the paper with a sheet of acrylic I got developing times over 30mins, but I switched to glass and this works much better at around 10mins, even with double-coated paper. My biggest print so far has been a 20x60cm panorama which I exposed from about 30cm and got an evenly exposed print. I think the larger 100W lamp will be the way to go for quick prints bigger than A3. Other reviews complain that it gets hot. Yes, it does, but it's designed to dissipate heat and will cook cyanotypes happily all day if given ventilation. Mounted properly it doesn't even need to be touched. I've also seen complains that it's underpowered, but I've managed to make cyanotypes in under ten minutes so I can't concur. It might be a case of using the wrong material to cover the print during exposure. I'm really pleased with this purchase. It came with a UK plug, was easy to mount safely to avoid touching the hot lamp and the UV-A is relatively safe. And I'm getting really nice cyanotypes at a nice quick rate.

Used this lamp to make a uv light box for cyanotype printing without having to rely on sunlight and it works great. I wasn’t sure which option to go for between 50w or 100w but I did a quick test exposing one half of a print for 10 mins and the other for 5 mins from a distance of around 15cm and the print came out the same on both sides. So 50w is plenty powerful to expose a print in 5 mins or less. It came with a UK plug despite the images shown in the listing.

As above the light was good but in order to thread the wire through the hole I had to remove the on/off switch and the only way to do this as it is a sealed unit was to cut it off which meant that I had to fit a water proof connector and extra wire in order to make the connection between my switch and the position where I wanted the light

It works great , nice and compact . Dries the uv resin in no time .

Yes the light is as described I got it wrong so sorry it works perfectly

It is incredibly small and the cable is very short. Not sure how it is supposed to be waterproof outside in the rain unless you have a waterproof socket outside near where you need the UV light. A longer cable with the switch half way along would be really helpful. On a positive note the light is quite bright for 10 kw.

Great product, used it to get rid of coffee stains. Good Price.

Loved this black light, we used it for a neon party and it lit up the entire room. Didn’t get hot and has a metal bar at the back so it can stand by itself or you could use it to hook over something on the wall. Long cable means we could plug it in a floor plug and still hang it under the ceiling.
