UV Lamp Comparisons for UV adhesive cure

Many adhesive users are hesitant to use UV-cure adhesives due to the requirement to invest in a UV lamp. The expenditure can be off-putting – particularly if the assembly is still in the prototype stage.

UV lamps can be bought for only a few dollars all the way up to several thousand dollars and needn’t be purpose built for curing UV adhesives – we have seen customers using nail polish lamps and tanning beds for curing adhesives!

It is important to remember with all lamps, bulb life is limited – even if the lamp still appears to be working, the spectral output declines over time (so adhesive may take longer and longer to cure). LED lamps have a much longer lifespan and don’t tend to suffer the drop off that other bulbs do.

Here are some lamp suggestions:

3 WATT UV LED TORCH

UV lamp 5

Price: <$10

  • Performance: Extended cure time will be required due to low output.
  • Suitable for: Very small one-off applications, prototypes and jobs where there is no power supply.
  • May struggle to cure through UV stabilised or coloured plastics.

 

BATTERY POWERED MONEY CHECKER

UV lamp 1

Price: <$10

  • Performance: Extended cure time will be required due to low output.
  • Suitable for: One-off applications, prototypes and jobs where there is no power supply.
  • May struggle to cure through UV stabilised or coloured plastics.

 

UV NAIL POLISH LAMP

UV lamp

Price: <$30

  • Performance: Fairly fast cure
  • Suitable for: Small applications or a low volume production line (such as jewellery)
  • May struggle to cure through UV stabilised or coloured plastics.

 

26 WATT FLOODLAMP

UV lamp 6

Price: <$200

  • Performance: Fast cure
  • Suitable for: Large assemblies such as glass bevels, glass furniture etc.
  • Can be mounted on a stand / used on a production line.

 

250 WATT FLOODLAMP

UV lamp 7

Price: <$1500

  • Performance: Fast cure
  • Suitable for: Large assemblies such as glass bevels, glass furniture etc.
