Hi Leaby,
To make a short test, you don't need to buy a UV lamp. There are two issues to consider with lamps:
a) over curing - i.e. excessive heat during curing because the lamp is too bright for the product, and
b) under curing - so the product is not correctly cured.
The risk of under curing can be minimised by simply doubling the minimum recommended cure time. Once the product is cure i.e. the chemical reaction is done, throwing additional UV light at it won't have any effect. So increasing the curing time is never wrong.
If the product / lamp combo over cures, you will know this. For test purposes simply either use a low power setting if your lamp has this, or flash cure for 10 to 15 seconds, before curing for the recommended time in the lamp.
Obviously when you chose a product and use iton customers, I totally recommend using the brands lamp.
BTW, HEMA-free and hypoallergenic are different. Hypoallergenic means the product contains no known and proven allergens.
